It's more reliable then on linux though, and windows has been doing "auto HDR" for videos for years, so kinda hard to tell when something is HDR or not there.
What grinds my gears is that HDR output in a lot of software is "Mac only", even though Windows supports HDR video output just fine, and has had support for wide-color and HDR since Vista!
E.g.: DaVinci Resolve has HDR capable only in its Mac version.
Similarly, generating a Dolby Vision file is basically impossible on Windows.
"Just buy a Mac" seems to be the best and most practical guidance I've seen for HDR workflows...
