I just received an update (may be old but I just got it, my Xbox One S was disconnection from the WiFi for months without knowing, as I’m not a huge gamer) with an HDR Dolby option. Two things, One, I thought both the One X and One S would only ever pull off HDR10. Two, I’ve read multiple reports, but never tried it myself, that the update for Sony TVs with the X1 Extreme chip only had enough power for HDR Dolby thru streaming and not thru an HDMI port, where HDR10 would be the only option. (In this case HDMI 2 or 3) I now have an HDR Dolby device (XBOX One S) plugged into HDMI 3 and now getting HDR Dolby. I guess those people were wrong in reporting that, as I did not get any new updates on my Z9D since the update with HDR Dolby. (Still waiting for Oreo 8.0) I guess my question is, dose anyone know how much this HDR Dolby is limited? I know to watch an HDR Dolby movie (without streaming) you also need a physical copy of the HDR Dolby movie (which most are HDR10 only) to go along with the HDR Dolby TV and UHD BluRay player. I’m guessing most games are only HDR10 as well? I have multiple HDR games and even before the update they looked amazing, and sure they are only HDR10 anyway. I’m curious to know if the Xbox is now capable of playing HDR Dolby movies on its UHD BluRay player, that would be an awesome surprise that I never thought would be an option.
