Samsung SM-T500 dull and washed out colors - Samsung Galaxy Tab A series Questions & Answers

Hi together, I just bought a SM-T500 and all in all i am happy with it. I mainly use it for webbrowsing and watching Youtube, Netflix etc.
I noticed that the colors of the display are extremely dull and washed out. Worse than my old Galaxy Note 10.1 (GT-N8000) from 2012, which should be replaced by the SM-T500. I can't really imagine that the panel used in the T500 is THAT bad. Unfortunately there are no proper display settings at all, so I am stuck with a display that looks almost like greyscale compared to other displays. (I know that the colors of an LCD are not so rich and vibrant compared to an AMOLED for example).
Is there any chance I can get around this problem with a custom rom?
I just recently learned about widevine. Does a custom rom break my widevine L1?
Thanks in advance

Is there even a custom ROM for T500?

Is there a custom ROM for T500 that fixes color temperature? Its own blue light filter acts like a bad blue light filter from the Playstore.

[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

[HELP] OP2 Increase Colour Saturation

Guys i recently bought the OP2. I noticed that display colours look washed out. Red, green, blue look dull and unsaturated. Is this a hardware problem or it can be fixed through software?
That's just the stock configuration, and can be changed in custom kernels. Have a look at http://forum.xda-developers.com/oneplus-2#kernels and decide if you're willing to flash a custom kernel (which generally do carry some bugs with them, mind you).

Color/display/sRGB hack/MOD for S4 / CM13 ?

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.

Badly calibrated display of Huawei M3

With each passing day, I just can't fully enjoy using my Huawei M3, the screen badly calibrated in comparison to my iPhones and Galaxy s7 (In basic mode). I purchased the tablet solely for watching movies and reading comics as it's one of the few tablets that has 16:10 aspect ratio but I can't use it as the colors are very inaccurate . Even the lenovo tablet that I've purchased for less that $80 has far better color that it is. It seems that a lot of colors are off but most importantly is that the gamma is obviously too high.
So my question would be:
1.) Does EMUI 5.0 improves the colors or it stays the same as it was originally?
2.) Is there any way to calibrate the display? I've tried Cf.lumen and it hits the performance quite badly.
Really???
I do not agree, for me the screen is very good
