Huge, immersive OLED, but 800R curve distorts productivity.

1. I currently have 2x LG 34GX90SA-W stacked. I put discord/teams/media on the top monitor, and browsers/work/game on the bottom monitor. 2. I need more vertical real-estate without having to crank my neck back to see my top monitor lol.
My wife has a LG 34GX90SA that she uses for gaming and work. Great monitor. Fantastic picture. Clear text in excel and other work apps. Even has smart os and a remote so you can use it as a tv. Only complaint is the shit speakers, but she has a soundbar so no biggie.
Lg ultragear 34GX90SA amazing i have one
800r on a 34” is pretty bad tbh. Makes it seem smaller than other 34” screens. If you’re set on 34” then you’re better off getting the AW3435DW or the MSI MPG341CQPX. They’re both 34” 3440x1440p with a 1700r curve which is waaay better. However they are glossy and QD OLED. For most (myself included) that’s preferred over the matte WOLED this LG monitor has.
I have a oled 34' uw from LG and I like it a lot! I tried 32' 4k ips on a Lan party side by side and liked the uw format a lot more. But I recommend to test both yourself as it seems to be quite the personal choice
Also a developer, I work, game and hobby code on a 34" LG OLED, never had a problem with text fringing or anything like that, the extra workspace is ridiculously helpful. That said, I use multiple editors and multiple applications on the daily, so I dont tend to have one window open in the same place long enough to risk burn in. If you're worried, and have the deskspace, maybe get a cheaper IPS for work/second screen whilst gaming? I cannot and will not give up that Oled look now, just too much better.
Im not sure on the exact model, and I'm not at home to check, but it's one of the LG ultragear ones. I havent used either mentioned in your post, so I can't comment on specifics unfortunately.
