Yes.  Because Bash is your login shell, it gets invoked as part of
spawning your X session.  Because of this, Bash-specific configuration
files affect your X session’s environment.

In my “~/.bash_profile”, I wrote

    export PROFILE_MESSAGE=HI

Then, I logged out of GNOME and logged back in to GNOME.  After that, I
opened a program – not a terminal :) – from GNOME Shell and confirmed
that it sees that “PROFILE_MESSAGE” is set to “HI”.

Did you log out and in again?
