PS3--Denon 3313(video conversion set to off)--VT50
Just recently, I put the Spears disc in an Oppo 103 and checked ycbcr 444 and RGB 444. I found that with ycbcr the pure direct mode did make a positive difference on two patterns, so I was using it. On RGB, it had some negative effect, so since calibrating using the PS3(1080p/60 and RGB) and Mascior's disc here, I cut 1080p pure direct off.
All this would be more simple if Sony did not treat apps as games, and output stuff like Amazon, Netflix and Vudu at RGB instead of what the PS3 is set at.
