Purple tint at the edge of the screen and shadows of dock application

Hello, I have an issue with the display on my Macbook Pro 2017 nontouchbar 13 inch

I just realized my macbook has some pink/purple tint at the edge of the screen and it can be seen on white background, other background color is fine.

And also on the bottom display starts appearing feaded shadows of dock applications. Those shadows are bearly seen but still are, it looks as they are burned on screen.

Any idea of this? is it firmware issue/hardware? Thank you
