Every player, even when in its Source Direct mode, scales the 4:2:0 content on UHD 4K24 discs to either 4:4:4 or 4:2:2 because the HDMI 2.0 specifications do not include 4K24 4:2:0. So you can't say "untouched". Madshi mentioned that he hopes to find player manufacturers that might enable 4:2:0 output.Thanks for that useful information. So when in source direct mode, the LX500 hands over the original video and audio to the pre-pro without tampering with it - is that right ?
What benefit would the LX800 give you over the Oppo 203 when used with the Envy?
PS - I suppose the HDR metadata would also be handed over to the pre-pro. Have you connected the Envy between your pre-pro or AV Receiver and your display device ?
HDR10 metadata is, of course, passed along from the player but the Envy doesn't need it since it examines each frame of the content.
