Ipad Pro: Burn marks on screen

I was wondering ouch there was anything that can be don't about burn marks on my screen. It looks like it's related to the case, as it lines up with the edges of the magnets.

It's an ipad pro, 2018, 12.9. It was bought in Nov 2018, a few days after it was released at an apple store.

It has a clearplex screen protector from best buy.

The case is a UAG metropolis folio case.

My pen also had burn marks where the magnets are. the associate at the store said it was normal, it was due to dust getting in between the magnets.

Everything was bought pretty much on release, which I usually don't do to avoid getting items with the technical issues that things have when they are first off the line. Other than these issues, and it getting pretty hot at times, I've had no other issues. I fell like if I had got a lemon, the issue would have come up sooner, but who knows.
