Digital BW, The Print

I have five year old Epson's Enhanced Matt that have been hanging without glazing under fluorescent lighting. The base is now a buff tint.

Do you know why it is now buff?  Is it brightener "burnout" or something else?

Out of curiosity - - - have you shined a UV light on it to see whether the brighteners are still there, still work, or have "gone off" in a splotchy way?

Thanks for the agnostic print url.
