So it gets a little lower when you bring it out in the cold, but presumably they measured it again at room temp. I'm not a physicist but I have to believe when it warms up again the pressure comes back up.

Depends when it was measured. They've said it was done during halftime, which is 15 minutes in the NFL. That's not very much time for equilibrium. They also may have been measured on the field, we just don't know right now.
