Very true, and nowhere more apparent than with ColorVision's software, since 
it allows you to use the same engine to read a target with both a scanner and 
a spectro, and therefore shows quite clearly which improvements are caused 
specificly by using a spectro. The same is true for Monaco's packages, its 
just not as clearcut, as the bump from scanner based profiling to spectro 
based profiling is to a different product. In either case metameric 
variations effect the accuracy of scanner built profiles more, since there is 
not a single contolled light color in scanners as there is in spectros. So 
what the scanner sees may be different for one scanner from another; and 
neither one may match what your eye sees.

Even a spectro can have difficulties with the worst of the metameric pigment 
inks, but its a vast improvement over scanner profiles for these problem 
situations.
