I guess, the response of a CIS scanner is probably rather comparable to narrow-band densitometry (like ISO Status I). Btw, does anybody know, for which applications and in which cases Status-I densitometry is actually used?

But anyway, the composite (light source + sensor) response of a scanner with CCFL lamps (which typically have rather tri-band phospors, and not broad-band F8-like ones), even if combined with RGB filters with smooth, broad-band shapes, is IMO far-off D50/colorimetric either.
