The paper is measuring the deltaE values against the CIE standard observer.
If they had put DCI XYZ in the table, it would have come out with a deltaE of
zero. This doesn't make it perfect. In fact, as the CIE 1931 standard
observer includes a factor that makes purple look like red+blue, you might be
better off matching using the CIE2015 LMS standard (better check the date, it
has been about to come out since 2007).

Hi Kirk,
thank you for your comment. No, *I* will not (be able to) match anything
against anything ... :-) But others who may follow the thread may be in a
better position...
Best regards - Hening.
