OLED lines in gray screen

[Knight]

Hey guys, so recently I noticed something was off with my TV, LG C3 evo, I got it last year around march with a 3 year warrenty, the screentime is almost 1600 hours now, right now I could just contact the store and go through the warrenty process and possibly get a replacement but what I've been hearing is that this issue is a thing with every OLED panel, some have it a little and some are worse, it's really a lottery and if I get a replacement I could end up with something worse than what I got on my hands right now.


I would take a picture of my own screen but it's just not showing up on camera, so I'll just link this reddit thread which shows what the problem is:

I noticed it in games like Silent Hill 2 and Alan Wake 2 after that I looked up grayscale tests on youtube and it shows up on both SDR and HDR. I've come up with sort of a solution, I use pretty much the factory settings in HDR and then I saw this black level option which is set to 50 by default, I tried lowering that and that somehow gets rid of the gray and turns those elements somewhat more accurate black and gets rid of the deformities but it costs some detail level loss and even in brighter games like God of War Ragnarök and Ghost of Tsushima, certain dark areas are sort of too dark, I just can't find the soft spot here so I'm reaching out you guys for advice.

I've ran manual pixel cleaning like 2-3 times, I don't see much difference and the main deformity I'm disturbed by in the middle of the screen isn't going away. I would very much like to hear what you guys suggest in this situation cause I'm just out of options here and not sure if the warranty claim would be even worth it.

1600 hours? That's nothing.

Try messing with the black level with HDR off. HDR is fairly pointless outside of movie viewing for the most part

Yeah that's what I've been trying to do but can't find the right spot, I either end up putting it too low or too high, either lose details or the dirt and lines still appear some times, that's why I just decided to ask here what do you guys recommend, currently I have it set to black level 40 with HGIG and everything else on default.

Right now, I still see lines in some areas in Silent Hill 2 remake or some areas in Ghost of Tsushima are too dark, not sure if I should switch to dynamic tone mapping, I just don't like DTM it's too bright for my eyes, I'd have to drop pixel brightness.

Nah man I give up, I really can't find the right spot or maybe I should be tweaking something else too? Right now I'm leaving it at:

black level 45
black and white stabilizers 10
game contrast 100
game colour depth 55
Dynamic tone mapping set to HGIG and oled pixel brightness set to 100, all AI settings turned off and image clarity and motion settings.

It seems that I shouldn't be using Silent Hill 2 remake as a base for this issue to begin with because the "black floor" or something is elevated in this game and somehow there will always be a gray room from what I understand, I don't know too much about display settings that's why I prefer to keep everything at default, I know going down this rabbit hole can be like this.
