I know, I just hope the linux kernel fix will come one day and allow full HDR10+ playback in CE.

That would be great !

Just curious is there much media out there that is HDR+ ? And if so are you able to rip it properly? 

Yes.  More and more every week.  Discs are starting to come with HDR10, HDR10+, and Dolby Vision.

And yes it appears to rip to mkv just fine.  Or just do full disc backup and playback that way.
