After some thought, it could be my display with regards to the 1080/24p issues on the chroma burst. My display has always shown an error there with 1080/24p no matter the player, but changing to 422 or RGB made it pass the test. I NEVER tested 1080/60p in (player handling 3:2 pulldown), so all this time I thought it was failing because of 444, it appears it was failing because of it's handling of 444 with 1080/24p activated from the player.
The 2011's, with a 24p input, have a setting of either 48hz, 96hz, or 60hz. If you set them to 60hz, they do not flicker like the other modes, but it's not just the standard 3:2 pulldown mode, there is some slight frame creation going on to smooth things out, which causes artificats. It obviously causes issues with 444 color space too. So, as far as the color space fail, I gotta blame that on the display, the only knock on the 5007 would be it cuts off a hair of the left edge outputting Source Direct or 1080/24p. I know the display has no issues here, because Ive tested it's 1:1 mode in all kinds of ways.
