Screen flex on ipad pro 2020

Hello, I recently noticed that even slight, normal pressure on the ipad causes the screen to flex a bit, as if it were initially protruding and the pressure pushes it back into place. It is especially noticeable when writing on a flat surface, not on my lap. Also I see it better when working with text - i see the text being distorted.

Here is a video i took of the problem :

Can anytone tell me if this normal and whether I have to take it to the apple store?
