As a colorimeter, a 3 LED scanner is likely to be far worse than a white light based/filter/CCD type scanner, since it's narrow band rather than the broad band responses that the CIE observer requires.
That's very interesting, given that LED / CIS based scanners are said to suffer far less from metamerism problems when used for profiling than CCFL / CCD based ones...
I guess it could be the case, if a narrow band scanner is used for "process measurement" rather than actually measuring the color.
