I’ve just connected the ATV4K to a new 4K TV which supports DV/HDR10+ via an AVR. Firstly, when connecting direct to the TV, sans AVR, the ATV Video Format is “4K Dolby Vision” & the TV temporarily displays the Dolby Vision logo as well as adding extra Dolby Vision picture modes within its settings. But when the AVR is introduced, the ATV Video Format is “4K HDR” & the TV doesn’t indicate any Dolby Vision detection. But when testing Dolby Vision content on Netflix, the DV tag only appears within the program’s summary description, leaving my unsure if the DV data is being passed through the AVR. Is there a better way to confirm this, without having any UHD BD’s at my disposal? YouTube App on the ATV maybe?
