Currenly not.

You can call on the device GetAppliedConnection(), which gives the
settings as they were during the last activation (or during the last
Apply call). Theoretically, you could say, if that differs from the
profile, it changed.

That might be useful information, in particular, that would be good to
see in `nmcli device` output.

Not at the moment. But would also be useful!
