27MD5KL-B

The LG 5k monitor 27MD5KL also doesn't have any vignetting and it has the same panel as the apple studio display 1. It can also usually be found used for around $400-600.

Unfortunately not. There are some really old LG panels but they cost 1k+ https://www.lg.com/us/monitors/lg-27md5kl-b-5k-uhd-led-monitor

I was not a fan of the proart 5k it had too much backlight bleed and an ugly matte coating. The Viewsonic VP2788-5K for around $900 was much better in those regards. A used LG Ultrafine 5k (27md5klb) for $600 is also quite nice with its bright glossy display.

It's been a while, but from memory, at the time, the Dells used the same IPS screen as the studio displays, but a whole lot cheaper. Dunno about now, but you could find what screen the studio display uses (i.e LG, Samsung, etc.) and then find other brands that use the same screen, at least compare t

Using the LG 27” 5K monitor 27MD5KL-B. Thing is amazing, but it does not swivel to portrait mode, had to buy a vesa adapter. It’s DCI-P3 99%. Edit: nvm, I see your budget is low, you’re not going to get color accuracy with $200. My monitor used can be found anywhere from $400-600 USD on Marketplace.
