I have an issue with my screen. Just not sure if it's worth exchanging, or if it's all to do with the screen type. I just don't want to jump to any conclusions. Some have reported similar issues, but not a huge number of people.
White definitely doesn't show through super white. It has a tint of yellow, compared to a friend's Galaxy Nexus. This is more noticeable at lower brightness levels, but still there when at full brightness.
I am seeing some vertical bands in darker background colors, no matter the brightness level. That seems to be more with the technology of OLED.
This one bugs me the most. When I tilt the screen away from me, even at a minor angle, white begins to turn to a blue tint. Starts occurring at as little as perhaps 15-20 degrees, and by the time I am viewing it from a 45 degree mark (from any direction), the screen has a very blue tint. Very noticeable when web browsing (Google search results pages being an example). My friend's Galaxy Nexus hardly does this, if at all. I find that very odd. Tested on identical settings. Neither of us had screen protectors and we bought them at the same store and in the same hour.
I'll probably go to the store and have a look at the demo model. If that one doesn't experience this, and if few of you haven't, I'll ask for an exchange.
