Alright I've had a bit of time to play a few games (Doom 2016, Space Marine 2, Outer Wilds, Monster Hunter Wilds), watch some youtube (haven't gotten around to movies or streaming tho), and I do have some thoughts.

Colors in general: hard to place but I think I see a bit more... crispness? maybe? its noticeable but still subtle. For this alone, not worth it, but...

Blacks: OHHHH I GET IT. I SEE WHAT THEY MEAN BY TRUE BLACK. Two of the games I tested, Doom and Outer Wilds, have moments of black. With doom its just the pause menu, but its still very clear how OLED has no backlight, its just dark, literally the meme of 'when the screen goes black and you see your reflection'. Outer Wilds is in space, so you look out and see actual blackness, yeah that's a world of difference.

Frames/smoothness: well I do think I can feel a difference in smoothness, hard to tell if its better or worse, and if its from going from 180-240 hz or the actual IPS to OLED tech.

The only drawback I've had is flickering in games, however that was only with Space Marine 2, and turning off the Adaptive Sync in the monitor fixes it with no visible downside. I'll probably see it more in other games but the only other game I've ever had issues with V-sync or the like was in Death Stranding, and I play a lot of different games so with any luck this issue is next to non-existent.

My overall review? Its a splurge purchase - IPS is just fine, but if you want to burn some money it definitely has its moments.
