@Yoeri What kind of proof do you have of Vimeo supporting HDR10? Does it work on any devices yet? Are there any sample videos you can point to?November update:
Philips entry split into two (EU/@TPVision vs P&F USA) because diverging rather than converging.
Also added vimeo and Kaleidescape (both HDR10 only).
Also, Vizio and Chromecast support DV, HDR10, and HLG. Oppo technically supports all three as well (I've found one HLG file to test that plays back via the Oppo 203 and triggers HLG on my Vizio P).
And YouTube supports HDR10 and HLG (upload and playback).
