Just for the record: It happened to my PP as well, starting only a few weeks after I had bought it.
I ordered a new LCD panel (along with a second Pinephone) so I could replace the screen when it would become unusable.
That never happened: After some time the unwanted ornaments stopped spreading -- now, one year later, they form a frame that is between 1 and 4 Millimeters wide (a little narrower than zetabeta's pictured above).
Even though that's annoying, it's mostly a cosmetic issue: The marks are not really visible when one uses the phone because they are hardly discernible when the screen is bright.
That said, I still don't think it's OK to sell such stuff and not replace it.
