but exactly this should no longer happen if you use 1.3.26.1
and explicitly EXCLUDE those images - because 1.3.26.1a _then_
will know this image can never be served in compressed form
and _not_ send any "Vary:" header for these responses.

This was the main reason for the 1.3.26.1a release at all.
You shouldn't downgrade and 'lie' to the proxies - instead
you should write your include/exclude rules more explicitly.
