Vudu is actually ditching DV in favor of HDR and I am more then happy with my Samsung KS8500. HDR looks downright amazing.

They are not ditching DV they will be supporting both formats. DV unlike say HD-DVD will just ramp up in support because a ton of movie releases are mastered in DV and projected in DV theatres.
No doubt HDR10 is the most "wide spread" implementation since well it's free, but it won't kill off DV especially with DV players and Medatek SOC's that support it expected to hit next year along with movie releases.
Samsung have already promised to update their sets to Dynamic Metadata, make of that what you will. The philips leak re. HDMI 2.1 was later altered so it's not exactly set in stone that it's going to be a new HDMI revision. I wouldn't be surprised if it was though and I sure won't be buying a new panel until we know what's going on with it. The consoles/GPUs will need updates too.
I'll wait and see what happens with Samsung I bet it's an "Evo Kit" like they rolled out for some 2014 TV's that added HDR support.
Would be great if this industry actually did not screw over customers when Dynamic HDR comes out, but I would not bet on it.
