2022 Hisense 58R6E3 blue color in corner

[pac.attack76]

Helping a guy out that brought this over last night stating there's a blue color in one corner of the screen and If you touch it with your fingers, it turns white. I haven't checked it myself just yet but I've never heard of anything like this before and wondering what would cause something like that. I'll try to get around to testing it this evening and get a picture of the front.
