Q: Iphone 6 plus screen edges colorization

Hello community

My ip6 plus has colorization around the edges of the screen in portrait mode. (As the phone is standing). It happens in all the apps I open.

If I don't open an app, i have a solid looking screen.

The colors I see are yellow, red, green, blue and just along the edges.

I am asking if anyone else is having this issue as my last iPhone 5 never had this.

Should I replace it with Apple.

Thank you
