I wouldn't worry about OLED for a computer monitor though.  Too much static content, too high a risk of burn in.

CRTs were prone to burn in and they worked fine on computers, that's why screensavers were invented. Yes some screens are going to burn, but they have a finite lifespan, personally I think it's worth it. Turn down the brighness and use a screensaver, that should go a long way toward preventing burn.

Screensavers sort of don’t exist these days because they consume power. The screen just turns off and the CPU goes to sleep  :-//

Of course they still exist, the fully up to date Mint system I'm typing this on has a whole selection of them available by default although their utility has been limited at best with LCD. Blanking the screen is probably the best screensaver you can use and is one of the many options.

OLEDs burn in much faster than CRTs.  The half life of CRT phosphor might be 20-50k hours, but an OLED is closer to 10k hours (at least for WOLED like LG's panels.) 

This is the same reason plasma TV burn in was always a bit overrated.  Panasonic panels had 50k+ half lives so burn in was much less visible over normal 10yr or so lifespan of the set.  I've got one with 20k hours on it and I can just about see a faint trace of a channel logo when on the solid green test pattern, but that's all.  Meanwhile I see plenty of pics of LG OLEDs with burn in.  (This is just painful to look at: https://imgur.com/a/qYD4QSK)

I'm going to be super careful with our set when we get one as I still can't help but be lured in by the damn infinite contrast!

They do, they're more like CRT based projection displays in that sense, but they can still be used for computer monitors, especially if the cost is such that you can just figure on replacing the display every 5 years or so.
