The screen damage resembles the damage of liquid of other LCD-based phone screens, see for example https://i.imgur.com/0p4p26V.jpeg for a similar liquid-damaged screen. There are thermal safety-related warnings in the wiki now (see https://wiki.pine64.org/wiki/PinePhone#Thermal_Safety), I would exclude damage to the UV glue itself at these low temperatures as possible cause in any way however.
It's possible that these are bad apples, considering the low amount of reports of similar issues. Replacement screens can be bought under https://pine64.com/product/pinephone-5-9...ch-screen/ if you want to spare Pine some money, if not you can open a ticket under sales@ in case of a fault already existing insidiously.
