HDR10+ (plus) support in Windows

[watchmn]

As the title says, I'm very confused about the support of HDR10+. 

I have an OLED TV that supports HDR10+, a AVR that support HDR10+ pass-through and an HTPC with Windows 11 on board. 

Till now I've used MPC with MADvr, and I haven't been able to enjoy HDR10+ content, but I've read online that Jellyfin can play and pass-through the HDR10+ metadata in Windows. Is that true?

As a new user, does a movie with HDR10+ is marked by a tag (or it simply marked as a "hdr") in the movie card in the app?
