Esses testes são situações extremas, e ainda inpedem a TV de fazer seus ciclos de compensação.

Não. O Teste é 5 horas on, 1 hora off. Com tempo pra fazer o ciclo de compensação e todos os recursos ligados (dimming de área estática, pixer refresher, etc)

No final o que importa é o tempo total de uso com o mesmo padrão no local. Óbvio que o objetivo do teste é avançar o número total de horas mais rápido que uma pessoal normal levaria.
Mas vc pode traduzir isso pro seu tempo e uso em horas.

Apenas 6 meses e já se nota:

Com uso normal tem vários relatos de burn-in:

"I purchased an LG C7 55" OLED TV in 2017 and have burn-in from the included Netflix app - namely the red “NETFLIX” logo that appears in the lower right portion of the app’s home screen, as well as from the red horizontal progress bar that is displayed in the lower portion of the screen when video is paused/scrolled.
Aside, I also seem to be developing blob looking burn-in in the center of the screen from unknowm elements. It appears to be similar to the “human form” burn-in that Rtings noted in their OLED test for the TV playing CNN. I do watch news type programming, which tends to position anchors, guests and other presenters’ faces in the center of the screen. Unlike Rtings burn-in though, mine seems a little less defined (perhaps because I watch more varied programming, not just CNN).

In addition to news programming, I have also noticed that a LOT of regular non-news programming also positions people’s faces in the centre of the screen (watch TV and see for yourself - sitcoms, talk shows, movies, etc). Over time, the convention of centering faces in the video frame will no doubt age the pixels responsible for producing facial tones faster in the center of the screen than at the edges of the screen.

My panel has about 2500 hours, though a large portion of the time the screensaver was engaged because I often listen to music for long periods of time using the Spotify app (which reverts to screensaver after 30 secs). 2500 hours over 2 years equates to less than 3.5 hours of TV usage per day.

Also, my TV was never unplugged from the wall, and all the compensation cycles ran as programmed. “Screen Shift” was on, and I conscientiously tried to prevent burn-in by being aware of static content and reducing the OLED light and/or contrast when I could."

Todo ano nós ouvimos que burn-in ocorria em TVs antigas e que as modernas possuem recursos pra evitar. Mentira. Embora possam extender o número de horas, não há tecnologia nova desde 2017 pra barrar.

Quem compra deve estar preparado pra descartar a TV ao invés de revender ou reusar em outro cômodo no final do seu ciclo.
