Put the long story short: Oppo 83/93/95 are perfectly fine to handle video data handling & transmission via HDMI, but Sony BDP-S570 is not (no matter you set the color space to YCbCr 4:2:2, or YCbCr 4:4:4, or RGB) - it suffers from serious errors when manipulating the video data before output via HDMI.
My point is - even Sony BD player has this problem, what about the others? Without the benchmark report like this, who knows?
Just be careful.
