Yes, sorry, "~/.guix-profile/etc/profile" doesn't set XDG variables.
You need to set it manually like this:

  export XDG_DATA_DIRS=3D"$HOME/.guix-profile/share:$XDG_DATA_DIRS"

Do icons appear after this?

This is surprising.  Usually distros set it to "/usr/share", but it is
probably not important as it's a default xdg data directory.
