I'm honestly scared to get OLED.
From the beginning of time, gamers like to sit down, and play a game for hours on end. If that ruins a brand new tv, there's an issue with the hardware. Hands down.
MicroLED come save us!
Honestly, you really shouldn't be that scared--especially with the newer models of OLED. I've played games for hours on end on my Plasma and never got burn in from gaming*. Temporary image retention that went away after awhile? Yes. Anything like a HUD permanently seared into the corner? No. Fortunately, newer OLED TVs are more resilient to burn in than plasma ever was. If you watch/play at a reasonable brightness (like less than 150 nits) and vary your content (including your games), then it really shouldn't be much of a problem. If you're just going to be playing the exact same game hours on end, everyday, for several months to a year then yeah, you will probably get burn in eventually (and it'll come sooner the higher you have the OLED Light set). Out of the people that game on their TV, what percentage of them game like that? I'm guessing it's at the very least a minority and maybe even a small one at that. If that is the case, then most gamers probably don't have to worry about it. For the ones that do primarily play one game for months on end or other extreme use cases, then of course LCD is going to be more appropriate, but I don't think the same is true for your run of the mill gamer.
Second, I really want to address the thing about MicroLED being our savior. This isn't addressed to you so much as everyone on the internet that has virtually turned this sentiment into a meme. From what we know, MicroLED should be able to get much brighter than OLED without being pushed as hard, but there's no guarantee it won't have burn in issues as well. It's a self emissive display and every self emissive display made so far has had issues with burn in. Some may have had more problems than others, but CRT, EL, Plasma, and OLED have all been susceptible to it. Hell, LCD can get burn in certain circumstance and it isn't even self emissive like those others. For all we know, there may be other flaws or quirks with MicroLED we don't know about yet and won't know until they're out in the wild. I'm as excited for it as every other home theater nerd, but I've been into this hobby long enough to know I shouldn't count my chickens yet. I really hope I'm wrong though.
*My plasma did eventually get burn in, but it wasn't from gaming. The burn in was from the logo on the home menu of my Blu-ray player. Since I used my player for watching Netflix and Youtube in addition to discs, I used the player nearly every day for several years. It's only after that when the TV got burn in. I think the many, many hours of pillarboxed 4:3 content I've watched may also be causing some burn in now, but it looks more like subtle vignetting than anything. Either way, it took years to even get to that point. The real moral of the story is that if you're going to get the Geek Squad warranty at Best Buy just in case, make sure you get the 5 year and not the 4 year. If I had, I would've had an OLED sooner.
Got a question, when using Pc mode (but not having a pc connected) just setting the tv to pc mode and playing ps4/Xbox/switch. Does it matter what the black level is set to? High+full vs low+limited?
For regular tv use it's recommended to just go low+limited which is what I've been using both in and out of pc mode. But for pc gaming your suppose to use high+full I've heard.
I guess I'm just confused if pc mode (when playing console games) changes anything and means I need to switch rgb levels. I've tried high+full but I'm not seeing a difference.
I don't believe you need to switch to High/Full just because it's in PC mode. You should only have change it to match your source. If you do have a PC connected, you'll probably be better off using Full on your PC and High on the TV (assuming it doesn't switch to High automatically if you have it set to, well, Auto). For consoles, I believe it's going to depend on what they're outputting.
