Could you clarify a bit by what you mean? The studio display has a higher resolution if I'm not mistaken (4500*3000), do you mean the display is more vivid or has a better color space (DCI P3 etc) coverage? Thanks!
I’m referring to the scaling of the display. The reason that I say that macOS looks better is because it uses integer scaling on the studio display. While even after setting a custom resolution, (the defaults macOS chose for the Mateview were either really small or really large for my taste) the Mateview still has a bit of a blur to it in small fonts it is most noticeable. Whereas the studio display shows well because it was made with integer scaling in mind
