I did not think of this aspect of the lamp that I have suggested. It looks like I will have to find a light that provides a good representation of daylight for my own purposes.
PS: As I suspected, the chromaticity at D65 is way off. Even the Correlated Color Temperature (CCT) is off at 6347K. The other light settings are off, but IMO close enough for my purposes for now. I will eventually have to get a light viewing booth when I get into making fine art prints, one that includes UV for its D50 setting. I guess you get what you pay for. And the advertised CRI does not tell the whole story, particularly when UV is involved. FWIW I used the ISO 3664+ from BabelColor for my measurements and evaluation.
