I too had massive issues with UW including eye strain and poor support. The corner of eye stretching and/or HUD issues and/or proper vertical alignment issues etc drove me insane. Don’t know the current state of affairs but my time with a 34” isn’t something I miss.
I would do 32-35 inch 16:9 4K 120 Hz if there is such a thing. When I looked there wasn’t anything available and that too at a reasonable cost and so I went with the OLED.
