Blue marks/sports on iPad Screen

Hi everyone! I was looking for a second opinion on these new blue spots on my screen. Do they look like pressure marks to everyone else? I haven’t really used my iPad in the past week, so I really don’t know what caused this. The spots don’t show up on screenshots either. Does this mean I need a hardware change of some sort? Please advise, and thank you so much in advance! Any help is much appreciated! And so sorry for the image quality!
