You might try cutting back on the matte acrylic to let more of any natural gloss the silver might have show, or perhaps the MA is muting the silver a bit.
You've probably mentioned it before, but what is your current screen? It seems to be almost as dark as panel 2 in the 160 degree color bar shot (please forgive the missing "u" in "color", they cost a lot to use here in the States, so we conserve them whenever possible
).
