Forget burn-in, all 4K LG OLED panels have actual defects around the corners which can manifest after as little asView attachment 11374 12 months, here is my C2:

You have them if you check thoughI've never had those defects. But I have gone through 4 replacements on my B7. All at LG's expense. Amazing customer service but very poor quality control. First panel had dark grey vertical bars that could be seen in a lot of content. The 2nd had a blown subpixel that ran at peak white in the middle of the screen. All within the first year. Then the 3rd replacement lasted 4 years before the panel completely failed. LG even replaced that out of warranty 4 years! TBH that panel after 4 years was building up serious burn in due to the system UI and YouTube, despite me babying it.
Now I have a C1 that got replaced once due to horizontal grey lines that started forming along the sides, like a vignette. Despite the issues I'd see till go with LG because of their support and how well they can be calibrated. LG still has the best near black handling out of any OLED I've owned; compared to a half dozen Samsung phones, iPhone XS, Lenovo OLED duet tablet, and OLED steam deck. Their TV's all out perform in near black content. From what I've seen online the QD OLEDs have a ton of issues coming out of black (desaturated colors, green tint, lifted greys, etc). That matters a lot for film and cinematic games. Hellblade 2 looks incredible btw.
Following on from this; there's this too along the bottom:My C7 is absolutely wrecked. Not from things being left on the screen for a long time with subsequent burn-in; but premature pixel aging from repeated short exposures to certain elements. The YouTube app did most of the damage; they thought for some reason that it made sense for a native app on an OLED TV to have bright red and white UI elements (they should have modified it for OLED sets).
As I said, I'm extremely vigilant about anything being on the screen for more than a moment and most of these elements are there for a few seconds at a time, but they've still completely destroyed the picture. Anything Yellow/Orange/Red now is just a mess. The refresher runs regularly and the pixel shift is on (but if you think about it, pixel shift only effects the very outline of a given on-screen element, not the fill of it).
I really lost the panel lottery. Got just past the two year mark and it rapidly declined, just out of warranty.
I just did a full 22 point calibration on all inputs 2 days ago. Lots of full field patterns up. Found no dead pixels. This is a WBE panel on my C1 replaced about 6 months ago. Has less than 2000 hours on it.You have them if you check though

After 6 months it is not visible yet, also they are not dead pixels, it is the oleds seperating from the substrate near the borders, the actual OLEDs get damaged, with their structure destroyed instead of their brightness failing like with normal burn in (The brightness lowers but the actual pixel is still fully intact structurally)I just did a full 22 point calibration on all inputs 2 days ago.

That's like me, but it's plex logo for me.
And my panel has starting to have dead pixels on the corners. So now my TV looks like to have rounded corners...
Stwrting to do that after 2+ years. Just months after my extended warranty ends
Never noticed but now need to check mine.

Called it!
Every LG tv from the past 5 years, maybe even longer ago, will develop this visible defect.
TV reviewers and YouTubers who get free tvs are not really going to mention this, which is super weird, but literally 10/10 OLED tvs that I checked all have this defect after about a year. This includes B6 or B7, CX, C1, C2, G2, Sony A8. I have never seen one which didn’t have the defect I mentioned so..
Better not to check if you didn’t notice it xDNever noticed but now need to check mine. I have a B9
Sorry, direct link from Google Drive, must not be playing well with the site..
on my LG CX, the pixel shift goes OUTSIDE of the panel. so things on the edge like the windows "minimize everything and show desktop" button on the lower right often got cropped. so it seems my panel doesnt have extra pixels.Better not to check if you didn’t notice it xD
But the actual panel is 4000*2160 and it shifts the 3860 horizontal 4K resolution to prevent image retention so it is possible you’d almost never see it
Yeah this is nasty stuff, pixel defect with certain projection tech used to haunt me in my dreams even.There’s a lot of nice objective data out there on colour accuracy, black levels, peak brightness, motion resolution etc to help you make a decision, but there’s not much talk about the psychological cost of ownership.
Are you going to worry about the content you’re viewing, game or video, to the point that you limit that activity or obsessively check for damage?
If you replace your TV every couple of years, then I’d say that psychological cost is low, but if you keep a TV for ten years or more like me, at least 5 years as the primary set and then another 5 as the secondary TV, then that cost can be pretty high.
It was too high for me, I went for a high end FALD and don’t regret the decision.
Maybe close proximity of COG drivers (chip on glass current driver vs. voltage driven LCD ). I even remember some OEM wanted to heatsink their monitors (?) .Why is the OLED deterioration only at the edge?
