adv7619 color space conversion

I use custom board with adv7619 and video source quantumdata 804b generator and I have problem with color space conversion. 

Registers are set as :02-07 720p,1080i,1080p In - 24-bit YCbCr 422 Out:  from script ADV7619-VER.1.9c.txt

 

Grabbed image is not exactly the same when inputs is changed between YCbCr422, YCbCr444 or RGB.

Colours are same but on borders when colour is changed there is slightly different. Snapshots are attached.

 

Does someone have same behaviour? What can I do to improve this?
