There are other issues with respect to an LCD monitor in calibrating, however, and that is that most monitors, except some of the high end Lacie use only 8 bit look up tables, and unlike a CRT which has analog controls, the look up table has to be adjusted when you do a calibration to a targeted whitepoint or gamma. Because of the small 8bit table, you sometimes get banding, especially in the darker colors. Accordingly, you might be better off calibrating to native whitepoint and native gamma and let the profile take care of the difference.
