This doesn't sounds like a gnome-shell issue - it does show the authentication dialogs on polkit's behalf, but it isn't involved at all in the policy decision.

Looking at the two policies you mention, both allow the actions in questions for the active session on the *local* console, but have "<allow_any>auth_admin</allow_any>" which applies in the non-local case. So as far as gnome-shell is involved, everything looks like it is working as expected. To avoid those dialogs, either the policies need to be adjusted, or color-manager/packagekit need to be changed to not intent to perform the actions in question in remote sessions.
