I'm not sure about your setup.  The dialog shows up for me on Gentoo.

In any case, the problem is that the pinentry dialog is not showing the
filename or anything else to identify which passphrase is requested.  I
can't tell how to change that with GnuPG command-line options, although
I could conceivably write my own pinentry program and use that with some
environment variables to set the message appropriately.  So I don't
think epg.el can fix this issue from the Emacs side.
