[Q] Color Temperature - Galaxy Tab 7.7 Q&A, Help & Troubleshooting

Ive been spoiled by my previous Ipad, and the trinity kernel on my GNex that allowed me to adjust the color multipliers to have a perfect white balance on my screen. Now every time I use my galaxy tab I notice the very minor yellow/green tint. It makes the otherwise INCREDIBLE display much less enticing, So the question is, how can I adjust the color multipliers of the screen? I am rooted, and running ezyICS kernel, with my only complaint being the lack of color adjustment settings. Are there any kernels that support this for the p6800? Ezynow, do you have plans to implement this into your kernel at some point?

Galaxy S4 Adobe RGB mode, any real merit?

http://blog.gsmarena.com/here-goes-the-samsung-galaxy-s4-black-mist-hands-on-video/
This hands on from GSMArena shows an Adobe RGB mode in the screen mode settings. It seems to have taken the place of the "natural" mode in the GS3 and Note 2. My question is, do you think it will be drastically better than the old natural mode?
I've owned the GS3 and now am rocking a Note 2. Switching to natural mode turns everything lackluster, grainy, and dingy looking. It almost feels like its turning off some subpixels. The contrast goes down and whites look even grayer. I've tried using it a few times, but always get really annoyed and switched back to standard. It's suppose to bridge the gap and be more pleasant like the natural colors of an LCD, but all it does is make the screen look defective to me.
One of the biggest problems with AMOLED is that when you turn up the brightness, the colors also change. It's consistently saturated, but not consistently of the same color. Greens always make me barf, and there are so many kinds of green. The weather widget and Lord of the Rings trailers are good examples. Do you think the Galaxy S4 has improved on color consistency over varying brightness settings?
I cannot tell much from the GSMArena video nor have I seen the phone in person. But I would like to hear your thoughts if you think the S4 screen color fidelity has improved much from its previous iteration, with or without the new Adobe RGB screen mode. Or if you could link to sites that have examined this in detail with actual units. The more generic reviews like to absentmindedly say the "natural" mode fixes the color issues with Samsung's panels, but that has not been the case for me, and am hoping the Adobe RGB mode and Samsung's new 1080p panel might not be just the same old same old.

Spoke with someone today who had some hands-on, he's a guy who really obsesses over colour temperature too (like me), he said it wasn't quite as good as the Perseus kernel master settings for screen calibration, but did make a very noticeable difference for the better. Incidentally, it you're with a Note 2 you should try Perseus out. I would not be without its colour tuning now (just give yourself a while to adjust, its such a big change from the Samsung colour calibration that it takes some getting used to).
Galaxy S4 also have 4 manual mode to switch on and 7 automatic modes .....

Colour Temperature - Warm?!

So had my N5 a few days now and it's amazing - loving it (except the speakerphone but that's another story). Previously had the N4 and had all sorts of issues with uneven screen etc (went through 8 units to get a decent one) but the N5 seems to have very good backlight uniformity and colour uniformity and I'm really impressed overall. Keeping the first one which is unusual for me.
Thing is.... it's very noticeably "warmer" than my N4. This isn't necessarily a "problem" but I'm wondering how others are finding the colour temperature or whites on the N5 compared to your previous phones. Also - I used Franco's kernel on the N4 to tweak the colour settings on that and there's a test version for the N5 I flashed but the colour tweak stuff isn't there yet as it's a test version. Is there any other way to adjust the colour temp on the N5 yet - or is it too early for that?
Try screen adjuster on the play store.

Screen mode/what's your preference

Coming from years of owning Nexus devices, the dev community always came up with a way to calibrate the display to user preference. Importantly, Samsung added some built in options in order to tune the screen, some of which will lead to a more natural color gamut instead of the overblown colors that many displays come with.
So what's your preference? Since, we have RGB controls now, perhaps we can come up with some suggestions for others to use?
I use AMOLED Cinema since its a more accurate color gamut, especially when viewing photos.
Basic!
WQHD
Adaptive display
Red 50%
Green 75%
Blue 100%
Edge color didn't touch
Screen brightness at 50% all the time.

I actually wish there was a dynamic mode still available. I like the oversaturated colors of previous Samsung's.
Basic all the way, because that's the properly calibrated, natural one.

Is there a way to change the TINT of the screen?

I recently sent my phone back for a screen replacement. And the new screen is insanely greenish, not partially greenish, but greenish everywhere. After comparing it with other phones, I found that it was not a too-much-green problem, because the screen still looks off with green intensity reduced with Color Changer Pro. The problem is the screen's tint is off, which should be moved towards the megenta side.
And I saw that you get to manually control the tint on Xiaomi phones. There's no such thing on Samsung's One UI. I know you can control the color balance when you set your screen mode to Adaptive, but it's wayyy to saturated and like I said, reducing green intensity won't solve the problem.
So anyone got an idea about how I can change the tint of the screen? Thanks ahead.

Question Any way to tweak the color temperature/RGB levels on these things?

I got the 2021 oled version. Screen is crisp, but I'm used to the vibrant greens and reds of Samsung AMOLEDs with blue light filters on... this thing seems to be red and especially blue-heavy, with pretty weak greens.
Can this be tweaked?
You can make some changes to the color settings-≥ display -≥ color mode
