I mean I think they'll become less of an issue to the point where they aren't such a concern. Like CRTs got there, burn-in wise, back in the day. Yes you could burn in modern CRTs, but it was difficult enough to the point that other than a basic screensaver/shutting off the screen, you didn't worry about it. I think we'll see that with OLED as time goes on, and part of it will be related to brightness. The amount of fade a light has, and thus the burn in, is related to how hard it is driven. So if they are able to increase peak brightness a whole lot, get panels that'll be happily driven to 2000-3000 nits, then the normal operations at the 100-150 nits for desktop usage could well be so sedate it just isn't a problem. I mean they'd still burn in eventually, but it could become something that takes so long it is just never realistically an issue.Burn in and ABL is something that will never ever be "fixed" IMO. It's just inherent to the technology and there's no getting around it, they can only improve it up to a certain point. I'll still be keeping my 32M2V for desktop use and for certain HDR games that have a ton of high APL scenes where an OLED would struggle in.
The ABL issue will always be there too, but I'm just hoping they can get monitors more around the level of TVs. ABL isn't a big deal on my TV because it can maintain a fair bit of brightness over a fairly large area, even if the full field brightness is actually less than a monitor. The AW3423DW can do 250nits full field (though I don't know it is a good idea to do that for long periods) the S95B caps out at like 210. They also both hit about the same peak of a little over 1000. The big difference is at 10-25%. The AW3423DW is over 1000 nits at 1%, but down to 450 at 10%, falling further to 360 at 25%. The S95B is still over 1000 nits at 10%, and only down to 560 at 25%.
Net effect is you can have a scene that is not overall bright enough to trigger limiting for either display, but you can't get the bright highlights on the monitor because they are too much of the scene, but you can on the TV. If they could bring the monitor up to the same kind of range as the TV, brightness limiting would be much less of an issue in real-world content.
