I have read on AVSForums that most TVs convert incoming RGB signal back to YCbCr for processing unless we choose a special option to tell the TV to skip the conversion and output pure RGB.
On a Panasonic this option called "1080 Pixel Direct".
An easy indicator would be if the Color/Saturation slider is still working if we feed RGB signal into the TV, then the TV converts incoming RGB to YCbCr for processing and back again to RGB for the panel.
So basically we get another conversion step which may (or may not) degrade the signal.

IMO the best method , if you have the correct pattern, is verify the Chroma Upsampling Error.
i prefer directly see the results of the chroma upsampling to evaluate the quality.
