Interesting: in that sense 4k would have slightly better brightness gradiation: if you average the brightness of 4 pixels there’s a lot more different levels of brightness that can be represented by 4 pixels vs 1, which might explain the difference perceived even when you can’t see the individual pixels.
The maximum and minimum brightness would still be the same though, so wouldn’t really help with the contrast ratio, or black levels, which are the most important metrics in terms of image quality imo.
