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.

Oh it rips to mkv? That's great. Current status of Dolby Vision is not all that great. Hoping we see some advancement.
