Hi, I have 6 months old Sony Bravia 55" X800H, and I've been using it almost every day. Just a few hours ago when I'm setting it up for remote play (both Steam and AMD Link) I noticed some "dirt spot" on the top right area on the TV. It looks clear on a game menu with solid colors (FIFA 21), and more obvious on white color like in the picture below:

The first thing I did is wipe it with a soft cloth, I thought it is some actual dirt that got there somehow, but it doesn't go away. Then I thought it's what we called image retention with the TV shown static pixels for a long time (after setting up remote play) but I fear it something else. Anyway, is that what we call image retention, burn-in, or just faulty panel? Before this day I only use it for watching TV or movies, and even when I open an app menu, it was in dark colors so if it was already there, I couldn't see it.

Please help, thanks in advance.
