Need Help. Display Problem.

So Recently I have noticed Colors in my display. Reddish in Black Wallpapers and Bluish in Light or White Wallpapers or anything. Colors are like fading. More in the corners and little less in opposite faces. They don't come in screenshot.
Please help?

I have noticed the problem arises when the phone gets heated like when I use it while charging.... and then the color will remain for few mins untill it cools down.
