I'm surprised HiDPI is working so well for you. See my other comment but I'm guessing you don't run anything in WINE. Yes Fedora is miles better than other distros regarding HiDPI but there's still no way to force per-application scaling in Wayland.
I mean, Windows doesn't get a pass here - you still can't scale HyperV, or anything involving mmc.exe, but Mac's HiDPI support is flawless.
