I have tested my phone and I can also attest that a color shift happens at a certain brightness.
At at around 400 cd/m² the phone seems to switch either color profiles or enables the extra white pixels. If its a (faulty) color profile it can be fixed with a update, if its a hardware related we are boned.
You can look at that post, I measured my phone and the switch happens at exactly 72% (402 cd/m², 71% is 398 cd/m²), but this can be different at any phone so you have to try it yourself.
But i have to agree with Johan, the switch happens when many other phones are already at 100%. I keep my phone at 33%, thats more then enough for most indoor use in the subway and on cloudy days.

i think sony should be aware that a user might want to turn on FULL brightness indoor!!!
such an option for color adjustment to increase readibility should only happen if light sensor detected stronge light. otherwize it should keep colors intact without change.. or better, it should be option to such funcion to be turned on or off..
i believe it is a bug... because i noticed this issue yesterday, when my some of my screen colors turned to lemon color, even while i was indoor and it is set to auto-brightness..it was like that for a minute then it turned to normal... upon further investigating i encountered the issue the people experiencing here when i set it to full brightness.
i love the device..but issues with screen colors is unacceptable
what we should do now?

I hope it resolves the problem with an update .... or at least find a way to disable the whitemagic technology, without sacrificing autobrightness.

I am experienciing the same issues with bad color reproduction and I notice it doesnt seem to matter what brightness setting I have on either full or auto or power saving. I have a few observations, yellows look more like greens especially on solid colours such as banners on the internet check out the bbc sport site which uses yellow banners these are yellow on my xperia u but green on my xperia p! Yet a photo seems to show yellow clearly as yellow eg yellow jersey on tour de France photos. Even the smiley above is green on my xperia p butt yellow when I view this forum on my ipad. you camt expect us to be happy with these colour shifts what is going on Sony?

Bought the phone today. Same problem here, the colors change at 68% percent. Streets on Google Maps are yellow below 68% and ugly-green above.
