So, in my case, with Optoma UHD51A projector, the "recommended" display setting I get is [email protected] / 4:2:0 / 10-bit. Whether I stick w/this or force Shield to "4K 23.976Hz 12-bit Rec.2020", all my 4K HDR 23.976 content plays at 8-bit 4:2:2 BT2020, at least according to my PJ. Believe @wesk05 you mentioned previously that my PJ may not be seeing this as 10-bit as it is. 4K@60 HDR like the Sony 'Camp' clip do play/show at 10-bit 4:2:0.

Problem w/forcing 4K 23.976Hz 12-bit Rec.2020 w/my PJ is that I get no picture w/4K@60 HDR like the Sony 'Camp' clip. On the plus side, Amazon Prime Video 4K HDR play really well at 24p vs. leaving at "recommended" [email protected] / 4:2:0 / 10-bit and everything rendering at 60fps.

Yes, you can ignore the 8-bit 4:2:2 on your projector's info page.  As for the issue with forcing 4K 23.976Hz 12-bit Rec.2020 and no picture at 4K 60, is this with the Oreo update or did you have it before that? I noticed that when you set Shield to 4K 23.976 12-bit 4:2:2, 4K 50 and 60 output are also 12-bit 4:2:2. Maybe your projector doesn't support those modes (they are within HDMI 2.0a/b specs.).

Another thing that I noticed is, when I set Shield's output to 4K 59.94/60Hz 10-bit 4:2:0, 4K 23.976 is not listed in the whitelist of Kodi Leia, because of that when you play 4K 23.976fps content, the output is switched to 1080p23.976. I'm not sure whether this is a Kodi problem, Shield problem or a problem specific to my Samsung TV's EDID. Will have to look into this.
