I have a 49" QD-OLED panel. I have never been one to find visual artifacts distracting, but fonts were awfully jaggy in Linux to the point I spent a week tinkering with font config and almost switched panels to a larger miniled since code looked horrible. And I'm someone who was fine with horrible VA low res low quality screens back in the day.

The sub pixel geometry on samsung's qd-oled needs very specific font configuration to be correctly displayed, and even then it just stops looking bad.
