Camera alignment desirable/possible w/DVX?

I just read Scott Billup's book, Digital Moviemaking, and he devotes an entire chapter to camera alignment. It includes instructions such as "Align camera to desired colorimetry by adjusting color matrix."

Is this even possible with a DVX, or is this something that can only be done with a high end camera, like the SDX? And if it is possible, how desirable is it to actually get it done?

I tried a search on this topic but couldn't find anything. Any and all info would be greatly appreciated. :)

In cameras, there were three issues that engineers faced. White point, which adjusts the levels of the three tubes, registration, which adjusts the verticle and horizontal relationship of the three tubes, and the relationship of each tube and all three tubes to how they process information, controlled by set up, chroma relationship, gamma, and knee. Studio cameras even in the CCD era have these controls, but in the modern CCD camera only white balance (white point) is commonly included. This is not so bad. Registration went out with tubes. To loose registration you basically have to crush the camera (it is possible, but very rare). Chroma, gamma, and knee are all workable in post. Black set (and stretch) is nice to have, as is black point (black balance), but it is less important than white balance, and is also easily handled in post as long as it is not outrageously out of set.
