I've had OLED for a few years now – LG B6 and newer, Apple Watch (3 models), iPhone X to iPhone 11 Pro now – none of which have had any issues with burn-in or even image retention, and the image quality has not detoriated in any way. They all have OLED and I use them a lot.

In my opinion, OLED burn-in is pretty much a myth or occurs with unconventional (mis)use.

Until microLED is available, I won't switch back to LCD TV. Contrast is one of the most important qualities of TV, and nothing compares to OLED at the moment. KMA

I can see it on my iPhone as I said only under certain circumstances. The issue is there but there is different technologies used to mitigate the issue. On my Apple Watch I haven’t seen it, I still have my first one and it seems to work very well although slow as it’s the first one from the first day of release. Beolab 50, Beolab 20, Beolab 8000 x 2, Beolab 4000 x 2, BeoSound Core, BeoSound 9000, BeoSound Century, BeoLit 15, BeoPlay A1, BeoPlay P2, BeoPlay H9i, BeoPlay H6, EarSet 3i, BeoVision Avant 55, BeoPlay V1-40, BeoCom 6000 and so much else :)

I have an old Apple Watch Series 0 (the very first Apple Watch), which now lives in a drawer as a memento. It still works (albeit slow), but after ~4 years of use, the display is still fine. Then again, it did not have an "always on" display like my later Apple Watches.

On iPhone X, which I had for 2 years, the display was pristine the whole time. iPhone 11 Pro is better (brighter display), and still no image retention. I use the phone several hours a day (typing this on it now).

I think, however, it is entirely possible to have variances between batches of OLED displays – on phones, TVs, tablets, etc. Some batches may be more prone to image retention than others. I guess that's a bit of a lottery, as it's always been with the backlight uniformity and tint of LCD displays.

As for televisions, I never keep the same model for more than 2-3 years. So I admit: if OLED TVs do not age well, I never have a TV long enough to experience the detoriation :)

All said, I would not change OLED blacks (and contrast) for LCD's blackish grays with backlight blooming, bleeding and non-uniformity issues. I had plenty of those issues before OLED :)

Until microLED, OLED is king! KMA

I do not think OLED burn-in is a myth.  Whether it is something to be concerned about depends on your usage patterns and expectations 

Here's a test where they conclude that it's probably nothing to worry about 

https://www.rtings.com/tv/learn/real-life-oled-burn-in-test.  

Their testing is showing some image consistency issues after 8000 hours...  To which they say (to paraphrase), "no big deal, that's over 5 years of watching 5 hours / day" (and I believe the unspoken assumption is that a 5 year old TV is ancient so why should we care).

Change those assumptions, and it might be something to worry about.  I think many B&O owners plan to keep their TVs much longer than 5 years.  I know I do. 

Also, 5 hours/day of use is very reasonable, but surely there are some who will watch much more... especially when life/nature/govt is discouraging you from leaving the house.  Maybe you have a retired person living with you who watches all day.  This could easily boost the usage to 10 hrs/day (they watch 5 hours during the day, and you watch 5 hours between morning and evening).  Now, we're down to 2.5 years. This is not so good.  

This is why it's important for BeoVisions to more easily swap panels, and to B&O's credit, they seem to be moving in that direction.  It seems like a portion of the market looks at panels as somewhat disposable after a few years.  Alas, a BeoVision is much more than a panel...
