Do you have a camera capable of getting us a close up (macro) shot of the last two lines in that image?
From what I understand the TV EDID says that it supports 4:4:4 chroma, but the TV itself converts it back to 4:2:2 before it's displayed. So I'd love to see a picture of your set doing successful full on 4:4:4 chroma....
I'll get a picture up asap.
