I've compared 4 other Note 4s with mine, and they all have this color variation. One side of the screen has a very slight color difference. It's like going from bright white to off white. It's most noticeable on white/gray backgrounds. When reading a sentence, I can really notice the color change between sides. Being that I've seen it on 5 of them, I'm trying to just ignore it.. Anyone else getting bothered by this? If you can't see it in yours, open an app such as Tapatalk or Facebook and look back and forth between the left side and right side. Or possibly from top to bottom. The color seems to change in some direction on all of them.
