John,
If I understood you correctly, you are assuming the photo is printed on
the front surface of the glass. My understanding is that it is printed on
the back surface of the glass. So, in principle, you have the same number
of surfaces to reflect from, as in case of a photo behind the glass.
(The glass is providing important protection from UV, which reduces fading
of colors. I suspect, it is the same in case of the dyes on glass.)
Cheers,
Igor

If we compare these prints directly on the glass surface to a print mounted

It will almost certainly improve the reflection problem.
The glass isn't put in front of prints to enhance the appearance of the
print; it's put there to protect the surface of the print from scratches,
etc., and to provide a surface that's easier to clean.
Eliminating the extra reflections from the glass before the illumination
has even got to the surface of the print has to be an improvement.
