Noticing Screen Distortion in ipad Pro 11" while Writting with normal Pressure

Hi I have bought recently ipad pro 11 inch. Previously My brother had an ipad 8th gen.

I am noticing while writting my screen distorting a little even with normal writting pressure ( without tempered glass ) while this phenomenon is absolutely absent in ipad 8th gen.

Is this a normal phenomenon considering the laminated screen..What's your opinion ??
