Would there be any advantage using aluminum foil in the oven on pans by
placing the foil dull side up?...

So far with respect to the question, resources explaining this do not give
technical reasons for their explanations.

It makes no difference what side is up. This was explained on one of the
web pages (Reynolds or Alcoa) but I don't recall which. They also explain
why one side is dull and one is shiny. It is the way two sheets are extruded
back to back.

While it may make no significant difference, it will make some
infinitesimal difference.
