I just found this calibration article on the Sony HW50. http://www.projectorreviews.com/sony/hw50es/calibration.php
As usual, Sony provides a range of color spaces that tend to make using a CMS unnecessary. BT.709 is pretty close to the Rec. 709 standard. Color Space 1, 2 and 3 expand the gamut to varying degrees, with Wide 3 being the largest gamut of the three.
Our calibrations, including this Sony VPL-HW50ES, are normally limited to a grayscale calibration, along with brightness, contrast, color saturation, tint (where applicable), etc. Only in very special circumstances will we calibrate the individual colors, in which case we discuss why.
I wish they would say why. Anyone wish to speculate or comment on this article. I'm just trying to get a handle on what I should do when I'm ready.
Also Cnet had this to say about the Sony CMS.

Despite its potential though, we ended up turning off the Real Color Processing CMS, however, because it did nothing to improve the projector's one semiproblematic area, blue color saturation.
