I didn't answer you question about the color temp.

You have CRTs, and so you probably have all the controls to calibrate your monitor, independent of the video card. Good CRTs have a lot of control of the RGB guns, contrast, brightness, etc. So, if you wanted, you could calibrate your monitor and never bother profiling it. With a CRT or high end LCD, you can get things very close without writing anything to the video card. That is ideal, since now your video card only has to make very minor adjustments. So, your color is being adjusted using the analog controls on your CRT during the calibration process. Fine tuning is done in the LUT.

It's kind of like golfing with a full bag of clubs instead of a putter only. The woods and irons get you close (analog calibration), and you use the putter for the final finesse (final tweaks to the video card). Unfortunately, I'd golf just as well with either a putter or a driver and no other clubs. I'm that bad. I play once every 5 years, whether I need to or not!
