And just to follow up, some instruments (the Spyder) are
half way between, breaking the wavelengths up into a smaller
number of (presumably) partly shaped bands, that are then
further weighted / subtracted by the software. In theory
this may provide better display device independence without
the disadvantage the true spectrometer has of the XYZ weighting
shape being discretely approximated.
This is also a reasonable description of our reflective (patch
reading) tool as well: more bands than an XYZ colorimeter, but far
fewer than a grating spectrophotometer.
