I think everyone uses FM for audio.

In the U.S., the audio for both VHF and UHF TV is FM with 25 khz deviation. The picture is a reduced carrier AM using a single sideband.

I think everyone is using the same for VHF and UHF, doing
otherwise would complicate receiver unnecessarily and there's
no real advantage to that.
