Does Nvidia Shield truly supports Dolby Vision TV-led (otherwise known as STD-DV, Display-led, Sink Device-led)?
Why am I asking?
Because I have noticed that no matter what DV content I am playing, could be Disney+ , Netflix, Kodi, Just Player, Nova Player, etc.
(I tried all DV profiles. P4, P5, P7, & P8), I always seeing on My TV’s/AVR's (Denon X3800H) input signal information that it is "Dolby Vision YUV 422 12-Bit", which suggests the box (Shield) is doing some sort of Dolby Vision processing, i.e. LLDV/Player-led, and it is not a truly DV passthrough (TV-led), as a true DV TV-led passthrough to my understanding needs to passthrough in RGB 4:4:4 8 Bit tunneling.
When I play the same exact content with the same exact video players (Netflix, Disney+, Kodi, Just player, Nova player, etc.) on my Homatics R 4K plus device (and on my Ugoos AM6B Plus in CoreElec/cpm), I am getting the Dolby Vision RGB 8 Bit tunneling, which suggests it is a true TV-led Dolby Vision passthrough on those devices.
Also it dispels the suspicion of the TV (TCL 75C935) and/or AVR (Denon X3800H) as being the culprit (I am using the same HDMI cables, Ports, etc.).
I also noticed that in the Shield the DV picture is a bit more washed-out then in the Homatics and the Ugoos, suggesting it is a Player-led tone mapping and not a TV tone mapping.
I suspect that the Nvidia Shield 2019 Pro doesn't supports a true TV-led Dolby Vision.
Does Any one of you play DV content With the Nvidia Shield 2019 Pro and seeing in your TV’s/AVR's input signal information that it is playing in RGB 8 Bit tunneling?
NOTE: I don't have Low-Latency Dolby Vision (LLDV/Player-led) Enabled in the Developer mode, so it is not the cause either.
NOTE: I have the latest Firmware on the Shield (I think some ware around May 2025 it was released, 9.2.1 (33.2.0.326), If I am not mistaking).
but it was like this all the time way before, at least 3 years.
