Yes, and that appears to be the only difference. However, you can
still set the 0.3nm sensitivity manually, as far as I can see.

Forcing the scaling to 0.3 does not result in approach mode. Approach
mode includes approach RAIM and some additional accuracy that is not
apparent to the pilot.

So, if you fly an approach with 0.3 forced, and the approach
light/annunicator is not active, you are flying the approach effectively
in terminal mode.

Approach mode may also make it go in and out of suspend mode at
appropriate times, and sequence to the missed at the MAP.
