There is a computer application available from Sony that provides additional calibration controls that are not in the User Menu... I could see MEASURING RGBCMY and finding they didn't need adjustment (or that gamma didn't need adjustment) but if those measurements were never made, you would never know if the projector needed more attention.
If you use 3D you need a completely separate calibration because the projector's lamp level is set much higher and there is a color tint to the LCD 3D glasses and the only way to compensate for that color shift from using the 3D glasses is to perform the 3D calibration with a lens of the 3D glasses over the meter OR use the 3D glasses to characterize the meter so subsequent 3D measurements can be made without the 3D glasses (when you do this, the calibration software will create a color offset so the meter will "fix" the color offset from the 3D glasses without the 3D glasses having to be in front of the meter - but you do have to have at least 1 meter reading with and without the 3D glasses and the software has to support this sort of "compensation".
If the calibrator you selected is not familiar with Sony projectors, he may not be aware of the software application that supports more detailed calibration of their projectors. I distinctly remember using that software to make calibration improvements on a 1000ES I reviewed. I also remember the 1000ES being pretty good, calibration-wise so big changes weren't necessary. But improvements are improvements and every available tool should be used.
I just found the software again... took a few minutes. They call it ImageDirector 3.1 and it is for gamma correction (and I think it allowed color-by-color control so it's much more flexible than just grayscale with high and low adjustments. I didn't see it on the 600ES Support page, but it is on the 1000ES support page. You can't do anything useful with it without calibration software and a meter, of course. But you can get more "pin-point" correct results using that software (assuming it is compatible with the 600ES, it was compatible with some of the 1080p projector models also so I don't see why it wouldn't work with the 600ES. As I recall, it took me a while to get good results from that software as I had to learn what it was doing before I could maximize its benefits.
