What you really want is the ability to control R,G,B gains at multiple points across the grayscale. This will allow you to converge the guns to create a sensible grayscale. Traditional sets give you RGB (sometimes just RB) gains (hi) & cuts (lo) and this is sufficient to balance a grayscale, but the more points the better the calibration.
Then what you want is the ability to restrict the color gamut to a standard within the native color gamut of your set. The primary choices of projector and display manufacturers is often quite divergent from the standards. Samsung DLPs (my current display of choice) and a few others allow you to enter the xyY coordinates for the set's native primaries and then the coordinates for your desired gamut (709 HD or 601 SD for instance). The set will then create psuedo primaries that exactly match the standards. It's awesome. With a good calibration you can achieve perfect colorimetry. It would be great to see an iScan do something like this.
Similarly one thing the DVDO scalars do not yet do is compensate for primary differences in the sources. SD and HD have different color gamuts and it would be super cool if the VP50 could twist SD to the HD gamut. It sounds like the Lumagen boxes can do this. It's a very minor difference admittedly, but eventually it will be demanded by us videophile sorts, particularly as more things get mastered in the HD gamut (much HD is still mastered in the SD gamut).
Finally, I am all for more calibration options in the video processors, but if the processors are asked to do too much we end up harming the image due to only having 8 to 10 bits per channel going to the set. Say you need to lower the B component of an 8 bit RGB signal by half, you've reduced the possible steps in that channel from 255 to 128. This is likely to produce unavoidable false contoring affects and other problems. Folks are speculating that it won't be until we get 14 bits or greater per channel that we'll really be able to do serious calibration in an outboard device.
