Not really, if you have a discerning eye.
Any non-integer resolution on macOS is rendered at twice that resolution, and then raster-scaled down and anti-aliased. So, if you have MacBook with a 2560×1400 display and you select any other resolution besides that and 1280×800 (exactly half), the desktop render will be raster scaled.
To be fair, it works better than Wayland's previous behaviour because of the 2× rendering factor, but you can absolutely still see scaling artifacts if you look for them, and I certainly do. Ringing around text in a dark-mode editor is especially obvious.
The only OS that has gotten HiDPI right is Windows.
