A theory might be that certain Sony sets "communicate" with this player and some color settings get changed as a result.
Also it has been reported that some RPTV can have a "green push" that the Sony player might negate that effect.
I tried auto, 480p, 480i, 720p, and 1080i. While I didn't use a calibration tool, I did observe color palates during the change. For every setting, the colors did not appear to change. So, either the SD matrix was consistent throughout these settings or the color space was recognized by my Sony HS20 LCD projector and it made a compensating adjustment.
When I switched between the 975 and the S97, I could detect an increase in green saturation -- though it was not overt.
I reported that many LCD projectors exhibit a green push. Part of the issue relates to the spectrum of light which comes from the projector bulbs. This would imply that DLP should be susceptible to this phenom -- but I've don't recall hearing this observation regarding DLP. Also, I hadn't heard this applies to RPTVs. In fact, I thought most RPTVs are CRT-based. As a result, wouldn't they be immune to this issue?
I have also noticed that my Time Warner HD box does not switch color space correctly. For example, it will output HD shows through the S-Video and composite outputs. But, they are so green, it's laughable. If this is a measure for the difference in HD vs. SD color space, I would describe the difference between the 975 and S97 as considerably less and propose it may be due to another issue (other than color space conversion).
