Color/display/sRGB hack/MOD for S4 / CM13 ? - Galaxy S 4 Q&A, Help & Troubleshooting

Hi
I recently bought a OnePlus3 - which has a non standard sRGB color calibration - I think it looks beautiful.
With the recent firmware update, I can turn on sRGB but then the display looks kind of dull - it actually looks dull like my S4.
Question:
Is there a hack/mod for my S4/CM13 - I can use to get more vibrant (maybe false) colors, like the ones I have on my OP3?

Galaxy S4 already uses the dynamic display mode by default, which causes colors to look extremely vibrant and saturated.

CM13 has a color calibration option.

I am not able to get WHITE on the galaxy S4 compared to OP3 - using the settings / calibration.

The OP3 on the left has brightness at 80-ish% and the S4 at 100%.
Even if I set the adaptive mode to 'Outdoor' it is still a greyish/yellow-white compared to OP3.

I know it's an old post, but you can adjust the colour temperature to get the same effect.

[Q] LG G2 Screen at max brightness

Hello,
I wanted to ask how it is with maximum brightness at the LG G2? During direct comparison in shop my Samsung Galaxy Mega 6.3 (i9205) vs. LG G2 be a little smaller maximum brightness and white is a little gray.
on G2 I am only shifted the regulator to maximum brightness (automatic was turned off) Battery been charged enough.
Is there display mode such as the Samsung?
In review writen radiant display
I am imagined something better .
How satisfied are you with maximum display brightness and white tint?
Thank you for your response
Sincerely Andrew Gale

Dude. Which do you prefer?
Something like a screen, nobody can tell you if you'll like it.
And you're posting into a G2 forum; of course most people are going to say this is the best phone evar.
Go with the one YOU like best.
The LG will always be brighter and have better whites because of the different technology.

[Q] Difference in display of same S4

Guys I am a S4 user from more than 6 months..Today one of my friend brought his S4 which is in stock condition and 5 months old as well..His screen is way more brighter than mine..Yes I was shocked too..I m rooted and using crash Rom plus domination theme but that does not matter i think ..I tried several apps to compare like stock browser,lock screen and camera.His screen has much glow and more brighter than mine.Both the phones have adaptive display mode on.My phone screen looks like dull..I can't show u the difference in picture because of camera quality..
Left S4 is mine and right one is brighter one..May be in picture there is no difference..

improving the color saturation

I was just tinkering with my old S2 and I was wondering why the G3 doesn't have different color profiles like the S2 does. "dynamic", for instance, increases the already quite vibrant oled colors.
my laptop doesn't have an extraordinary screen but nvidia's digital vibrance make up for it quite nicely.
So, is there any way we can digitally enhance color saturation on the G3 on a rooted, stock rom? I don't mind the colors becoming inaccurate, I'm just a color nut (the only reason I'm not switching to a note 4 is the price).
Note, I am aware of the color tweaking you can do in the ease of access panel, but that only gives a small contrast boost before it starts to change the hues completely.
It doesn't have the Samsung tweaks because it's not a Samsung device.
The only colour Adjustment I know of is the one in Accessibility. Haven't heard of any others
Go to Settings > Accessibility > Color Adjustments, and set it just above the camera icon
Check out the screenshot
and put it exactly there
and BOOM... colors are more vibrant and more contrast to the display in general
Oh and BTW the reason is that the G3's display is an IPS panel while the S2 ( and most Samsung's phones) is an AMOLED display..which is by it's nature has more vibrant colors(more than I like) and deeper blacks than IPS displays

Think the edge+ is going to have that weird brightness programming issue?

Remember the regular Galaxy S6 edge? How it was about 60-70 cm/knits less bright than the regular S6 at maximum manual brightness in darker environments? This would be a deal breaker for me if this is the case because I like to ratchet up my phone on full brightness and experience all the best color reproduction at the highest contrast. Anyone with the early edge+ units confirm if Samsung did away with this weird programming? Edge+ and Note 5 should be around the same manual max brightness as the regular S6 and S6 edge.
S6 edge+ still has brightness bug
yes the s6 edge plus has the brightness bug. Checked demo units at all major carriers at the mall. Note 5 does not have the issue. Can't believe Samsung still has this problem. I will also pass on the edge plus and the note 5 does not have enough new features to make me upgrade. So I guess it is no new phone for me!

I can now also confirm that the "bug" is in place. It has to be intentional, because this is the second time it's specific to an edge variant. Whatever the case, I am going to have to settle for a Note 5. Which is disappointing, because the color selection is generic black or white. I wanted the edge just for that gold color. I am annoyed they couldn't bring the silver variant of the Note 5 to North America at least.
can one of you guys try velis auto brightness and see if that works!!!! im considering this device but i want to make sure I can also use it with out this weird brightness bug !!!

I can't answer to max brightness on manual-mode being different between devices.
But do want to let you folks know that max manual brightness will never be as bright as max auto brightness, even when using 3rd party apps such as Lux or Velis.
Just in case ya'll didn't already know.
I know, I've tried.
There are hacks (search my threads for the script I created) to make manual brightness just as bright as auto brightness, but the hack does not work very well.
I have the tmobile variant and it has this bug , very annoying how could they screw this up twice and on the best looking screen display they have ever made
+1 but
Is not a brightness bug. This is our limit I guess due to the curved screen edges...
And is not that bad at all people.
Only for 10% lower????....pfff take it who cares.
But yeah it's surprised me too.....at least they fixed that stupid sharp edges.
If this screen isn't bright enough for someone, they need to go to a doctor immediately.
It's not that it's not bright enough lol, it when max brightness dims when going into a low lighted area even with auto brightness turned off.
I'd have bought the S6 if the screen brightness could be manually adjusted from 0 to 600 nits like any normal phone. The S6 is not as bright indoors as an iphone and apparently despite all the customizations available on Android, this is still not possible.
The Note 5, however, has a bright enough screen that max brightness is as bright as an iphone. The Note 5 has a clearly superior screen to the S6. It's got to be a different panel in terms of quality. Had they made a 128 gb Note 5 I would have thought long and hard about a Note 5.
Samsung stop overthinking this. Unlock the full range of autobrightness regardless of whether we are out in the sun or not.
It's pretty obnoxious that it adjusts the brightness by itself even if it's turned off, it's unbearable if you're outdoors since it dims the screen so much on it's own:\. Is there not a fix?
Can't believe there's no official patch for this. Got a software update this morning and it did not fix it.

Does any ROM have display mode settings like Lineage's "Dynamic" or "Natural?"

Does any ROM have display mode settings like Lineage's "Dynamic" or "Natural?"
The Axon version of Lineage is conspicuously missing this much needed feature. Even ZTE's crappy stock ROM has a "Gorgeous" setting that livens things up.
Out of the box, the Axon's display looks low color gamut, with anemic colors, worse than most IPS panel.
I'm not looking for accuracy (we all know that the Axon's screen isn't accurate anyway) but deeper colors like an AMOLED display is supposed to have. The Galaxy S panels pop a lot more yet score much, much lower delta values than the Axon, which looks drab AND is inaccurate. At least give me POP if not accuracy.
