It is actually smaller. The attraction of more electrons toward the nucleus
make the nitrogen atom smaller than the oxygen atom.

At these conditions, yes.
The only difference I can see that has not been mentioned so far is that the
Nitrogen is DRY. Water vapor certainly does not follow the gas laws at these
conditions and the water vapor may condense at ordinary temperatures and
vaporise at higher ones, thus changing the pressure slightly. It seems to me
that dry air would be just as good as dry Nitrogen.
