So… there are 2 competing HDR standards, and HDR10 will probably win but anyway. They’ve only been available since last year, only in 4k TV form, and if you bought one you almost certainly know it. Monitors supporting it are almost completely unavailable at the moment, same with laptops, and OS support, and etc. etc. Basically it’ll be “supportable” at some point this year with all new, or relatively all new screens, and updated OS’s, and even GPUs require the right output type.
