I got my nexus 5 and was worried about the screen, but no issues. No dead pixels, the screen only slightly washes out when viewed at an angle (meaning only people nitpicky people would be annoyed by it. I personally think the screen is still easy to view, and read from even an extreme angle. But I have seen videos of others with nexus 5's that looked unbearable, so I'm sure the issue exists. Maybe I just got lucky and different screen hardware.
I dont really notice washed out colors in general, but the color temps are definitely different than my iPhone 5, which to me felt a bit too bright/blue compared to my nexus, easier on the eyes.
