The whole problem with this thread is that its assuming that everyone's vision is the exact same. I see there are people who are posting "I have a pure white one with no color shift." This then leads people to believe that a phone like this exists (which it doesn't, because OLED).
But I would be money that if the people who had the phone showed it to 10 different people in this thread that many of them would say there is a color shift, while some would say there isn't. The hunt for this perfect screen is ridiculous.
