So in short, the Apple TV for watching Dolby Vision material and a S922X in all other cases?
Is Dolby Vision technically possible on a S922X and just not implemented, or is it impossible?

Whilst Chipsets may or may not be DolbyVision capable and licensed - media player software (excluding Netflix, iTunes, VUDU) - for seamless DolbyVision Dual Layer Rips video playback is not. (ie. HDR10 base layer + seperate DV enhancement layer)

All sorts of DV Rip / file manipulation is needed first to produce Single Layer Profile 5 files, see HERE (click)
Even then only the Infuse App (click) on the ATV 4K seems to playback such Muxed and manipulated DV files properly.

As far a I know, that is it as far as DV playback has come on any mainstream media player software.
