Btw, Graeme, is there a reason why the default for the observer CMFs is not 1931_2, but J&V 1978_2? IMO the ICC requires measurements with the 1931 2° observer CMFs.
Not really, just that the J&V 1978_2 is mean to be the "fixed" version of the 1931_2 data. See page 5 of Mark Q. Shaw's thesis "Evaluating the 1931 CIE Color Matching Functions" <http://www.cis.rit.edu/mcsl/research/mshaw/CMF_Thesis.pdf>
