There's no difference.
22 years ago my instructor trained me to ask, before reaching the FAF on a non precision approach, "LX-xxx, please confirm QNH 1012?" and to systematically set the radio-altimeter alarm to decision height.
We do the same but we don't say the QNH we would just say "Confirm QNH". The idea being that we want ATC to tell us the QNH without being primed by whatever we've just said to them.
None of this helps if you have a French controller giving a QNH of 1011 in English to English speaking pilots and 1001 in French to French speaking pilots.
