OLED is bad ... not only it has the burn in problem , it is not bright enough, and it displays less colours when you change the brightness . The future is for Micro LED .. Thats why Sony Ditched OLED altogether for their new TV line up.
OLED is great - just not for all usage cases.
I certainly wouldn't get an OLED monitor for productivity or design work, for example; too many static UI elements, too much pure white for too long, etc. It's just a bad match.
With gaming, it depends - most newer games have had their UI designed with considerations for OLED, so static elements are frequently set to around 50% transparency, which, combined with the built-in burn-in countermeasures in the display, is usually enough to make it a non-issue. But, if you are playing an older game, like say, Baldur's Gate, where the screen is just chock-full of static UI elements, it's a bad fit.
In general, I, personally, just wouldn't buy an OLED monitor - I just don't like having to worry about burn-in on any level, nor having to adapt my usage to my display.
I had a final-generation Plasma TV that did a lot of monitor duty in the living room, and the fear of burn-in was always in the back of my mind. And it did end up with significant burn-in over its eight years of service (it was on at least 10 hours a day, much of it in Windows, as I worked from home), but it was still only visible on pure color calibration images.
Still, I switched to a 75" MiniLED TV when I finally upgraded, rather than an OLED, simply because I knew there was zero chance of burn in, and it's full screen max brightness is seriously impressive even in a bright living room. Newer OLEDs can get bright, sure, but only for 10% of the screen, for a short period. Great for HDR content, but can't compete with MiniLED if you need your whole screen to be pretty bright because of the lighting in the room.
I do have a 48" LG C1 OLED in my study as one of my monitors, but it is used strictly for gaming. It used to be my bedroom TV, but I moved into a bigger house with a bigger bedroom, and it was just too small for the room size, so I moved one of my 65" MiniLED TVs in there instead.
Watching TV, movies, or playing current-gen console games in a darker room, though, an OLED screen still blows MiniLED screens out of the water. I love the ones I have, and wouldn't trade them for OLEDs, but, used as a pure "TV" TV, as long as the room isn't too bright, they really are great.
To address your point on MicroLED screens - they are absolutely wonderful... if you can afford to pay the price of a brand-new car for an early-adopter luxury TV that won't look nearly as good as later consumer models that will cost a fraction of the price.
MicroLED is the future, for sure. But that future isn't here yet, and won't fully arrive for a decent while yet.
Comparing MicroLED to OLED today is like comparing current EV battery technology to one of the next-generation technologies every manufacturer is frantically researching to get out the door at a price people will pay. One of those technologies is actually available, and you can simply go to a store and walk out with a unit that uses it. The other is still very much in the development stage.
Of course future technology will be better - that's the whole point of developing it in the first place. But it also isn't an option unless you have unreasonably large amounts of money to essentially throw away. Saying current technology can't measure up to future technology is like saying water is wet; we all know this, but it's still a completely pointless thing to say, because it won't make that future technology arrive any sooner.
