ADV7627 RGB 4:4:4 Color Space Issue

We are using the ADV7627.

An error occurs when we have a source generating RGB 4:4:4. Output color is incorrect and exhibits lots of pink.  When the source is connected directly to the display everything looks just fine. BTW, auto-CSC doesn't seem to work in this case.

As developers, are we expected to read the AVI Info Frame, detect the color space, then set the HDMI Tx portion to output that format?

What is the strategy for handling color space?  How are other people handling this issue?
