More is not always better, I don't get this mania for "moooar brigtness" when I'm already running my traditional LCD far from peak brightness.
OLED's are not bright, and get washed out in bright rooms. Since they don't use backlighting like a LCD.
So I have an older LG OLED - a C6?. So not only is it one of the older models that doesn't get as bright, it has a few hours on it as well.
What Riccochet says is true - it does struggle if the room is bright. It's at it's absolute best when the lights are dim. I wouldn't call the screen dim, it has a peak output of around 600 nits, and if you had a pure white screen it could be blindingly bright, but it has a very aggressive auto-dimmer which will only let the brightness stay there for a moment and then it will dim the entire screen to preserve the contrast of the image (a nice trick to have when you have an infinite black level I suppose). Most of the time it isn't noticeable - you are watching something dynamic and the explosion only needs to be bright for a second, or the screen is sustained and it dims early on and stays dimmer for the duration - but it is present. But counter to that, as bright as the panel is capable of getting, I wouldn't want to run it at that level full time anyway as it would burn my eyeballs out.
That said, my biggest issue with it isn't that the screen brightness or the aggressive means needed to protect the screen - it is an issue, but compared to the contrast and color the screen can put out, it's a minor annoyance at best. My biggest gripe is the fact that the screen itself is glossy and reflects so much. Now, part of that does have to do with screen brightness, so I recognize it's somewhat related. I have to pull all the shades down in the room during the day or you can't see anything on the screen because of the reflections. The addition of an anti-reflective coating in the 2023 OLED models is the first thing that has had me thinking of upgrading.
But you can pry the absolute blacks and rich colors from my cold dead hands - I wouldn't trade that for all the brightness in the world. I guess everything has a tradeoff, it's just a matter of what you are willing to live with and pay for.
