I'm not an expert on that STB but that sounds right to me.
Also, it appears the Marantz receiver has a lot of video processing capabilities if one wants this. The Marantz AVR even has several picture mode (PM) options that are similar to the 77c8 PM options. I have the Marantz PM option set to "off".
My question is what setting on the Marantz AVR should I set the "4K Signal Format" to? The choices are either <Standard> or <Enhanced>. Normally, I have <Standard> selected.
When I select <Enhanced> I get a popup message that states: "Your TV is not configured to support 4K 60p 4:4:4, 4:2:2 or 4K 60p 4:2:0 10 bit video. Are you sure you want to use 4K Enhanced? <Yes> <No>"
Of course I have played around with this and have watched content in both settings. But, I don't really know what this means. I think I am seeing a difference between "standard" and "enhanced" but I am not sure. The Marantz manual does not provide any detail. Also, I do follow the AVSForum thread for the sr7012 owners (along with several OLED threads) and think this is the best place to ask this.
Ok simpler answer: you need to set it to "Enhanced" on the AVR, and
on the TV go to Picture, Additional Settings and turn "HDMI ULTRA HD Deep Colour" to ON.
Because the AVR is a sink device it is receiving the signal from the STB, so needs to tell the STB it can accept the high-bandwidth modes which are supported in HDMI2.0b.
Older models would just re-send the setting from the TV, and by turning "HDMI ULTRA HD Deep Colour" to ON the TV advertises that it can accept those high-bandwidth modes. But now you have to remember to turn it on in two places
if you don't, you can't get HDR (to keep it simple!). In my signature there is a link to a HDMI modes table, you can see how limited the modes are at the top with the setting off. Some older devices play havoc if they are connected to a HDMI 2.0b TV/AVR though, which is why that switch is provided.
