I tried this myself a week or two back.  The non-glop version does exhibit 
significant bronzing, reduced to almost zero with glop on.  This was on 
PermaJet Oyster.

As I understand it the Epson glop is applied only in the highlight areas 
where there is little pigment in order to equalise the gloss across the 
whole print.  I haven't done a scientific Dmax test with and without glop 
but just measuring a shadow area on each print shows no difference in the 
readings.

Hope that helps
