75" KE-75XH9096, green shade in the middle of the screen

[Hunter-PZ]

2.5 years after buying the TV, a green shadow appears in the middle of the screen. It is most noticeable on a gray background. It's not that noticeable when playing on the PS5, and it doesn't really bother the game, but it's there. Don't know what to do with it? I tried resetting the picture settings.

The TV is 0.5 years out of warranty, so I personally see this as Sony pushing me to buy a new TV.
