Same MBP Retina, very similar problem here for almost 2 weeks. The way the colours are distorted is not quite the same, but it may be well just a different representation of the same issue (I will try to post an image when I get home).
In my case, everything started while normally using the laptop: just checking some websites with Chrome and switching back and forth to an IPTV stream on VLC. Suddenly, everything looks a bit ¿saturated?, then it went back to normal; after a few minutes, the same problem again which continued intermittently, more frequent every time, until it finally became permanent.
Restarting, resetting the NVRAM and the SMC didn’t solve it. I just switched the laptop off and next day it looked the same, BUT… after a few minutes the screen recovered the original, normal colours. That last just for a few minutes, but it was there… only that it wasn’t for long. That behaviour continued; I also detected that, when the colours were distorted that way, the screen presented very clear image retention.
Last Friday I hooked up the laptop to an external 24” monitor, where the image is shown just fine. I left the MBP display as the secondary one, and it happens that… for 2 hours the desktop’s background image was fine, then it went distorted again. I created a white *.jpg with the same resolution than the screen, and opened it to full screen; when I do that, the display always fixes itself for a variable period of time.
I have an appointment today with a Genius, but guess what… I have been using the MBP for 3 hours now and the display is fine. I would like to show him how the thing looks when distorted.
If you find anything please keep us posted, I will do the same.
PD. Finally I cancelled my Genius appointment given that I couldn’t reproduce the problem today. And this is my screen:
