One important reason for UHF for the Sup'R'Mod, instead of channel 3/4:
Some TVs at the time had a built-in VHF antenna, and no external
connection for VHF! But, the UHF was a small loop or "bowtie" that
connected to a pair of screw terminals on the back of the set.
For example, the 17"?
They were available with a variety of connectors.
Some of those switchboxes had a short flat wire with spade lugs as
output for connecting to the TV, and for input had screw terminal antenna
input, and RCA for the RF input from the RF modulator.

You are correct for some but I do recall some with a composite output in
that little switch box as well. Maybe I'm misremembering from 50 years ago.
