Yeah the only 6k 32” options are 60hz.
Thunderbolt 5 being a thing now opens up the possibility of higher refresh rates at good dpi but they won’t be cheap.
The issue with oled brightness is how bright or not they get with a large light area. I was buying for well lit office use, if you have more control of room lighting dimmer monitors might be ok. Though there is the text issue too.
I wouldn’t have one for home use because of text clarity mainly, and the brightness secondarily but my home desk is near a window.
Good IPS screens have good contrast for critical image work. Their contrast and dynamic range can do better than you can typically print, although many sensors can capture more range than you can display. I cared about good shade with no stepping at low values (near black) so blacks not being “black” was less important than seeing all the shades
Also consider what you need it to be good for - your experience? A viewer seeing the image on a different screen? To get accurate prints? Etc.
I don’t know where you can try them sorry, but you also need a similar viewing environment. Maybe order somewhere good on returns?
