It is certainly the case that protection from the air will have a
significant impact on dye stability - simply because any deterioration
involves a chemical reaction, and without air and moisture(or any other
external substance) to react to such reactions will be limited.
I'm not familiar with the process of dry mounting, but obviously some of the
questions would be - the impact of the board (is it acid free?), how do you
separate the image from the mounting if the mount itself deteriorates with
time? These questions are more related to archival prints that you will be
keeping for 50-100 year at which point issues of conservation will come into
play and which adhesion to other media may complicate.
There is a school of thought in my profession (film conservation) that sees
acetate film vacuum sealed before being stored at low temperature - this
thereby removing issues of humidity. However it also lessens accessibility,
ability to examine film on a regular basis, and is resource intensive.
Sealing a photo, just like framing it or putting it in an acid free album,
will see a drastic improvement in print stability. You simply need to ensure
that whatever steps you take do not rule out any future options (for
instance restoring a photo that has been laminated could prove very
difficult)
