Since they had Engines and they were not in panic possibly they would have noticed too low gear and gone around.
Keeping it simple and safe.
I know I use 3 things before opening my mouth to say positive rate and it all occurs in a couple of seconds.
SENSE: if I can hear T/O thrust and I can see the attitude passing through 12* I know that we are probably airborne.
and
INDICATION: check IVSI
and
CUE: my peripheral vision confirms for me the ground is getting further away.
”POSITIVE RATE”

Hearing the engines are at T/O thrust ???? Probably airborne ????
+12° pitch might not get you off the ground if you forgot the flaps, or your engines are not at T/O thrust, or your speed is too low.
Peripheral vision is not reliable at night, or in low vis, or at airports such as Luton, Leeds or Jersey and others which have steep drop-offs after the runway, so the ground will fall away but that does not mean you are climbing.
The whole point of the positive climb call is that it confirms, by measurement, not by assumption - that the aircraft is climbing.
IVSI indicating positive rate + RA increasing + Altimeter increasing = Aircraft is climbing
