I definitely set my fatbike pressure at ride temp - 8 psi in the house can easily turn to mush on a cold day once the tires acclimatize.
As a less extreme example of temperature if you think of a mountain (like let's pretend you biked from Golden to the top of Mt 7), it's usually warmer at the bottom. Colder at the top so relative tire pressure lowers.
OK.
But, you also gained like 1200m so ambient air pressure changed too. Are your tires relatively more inflated as a result?
Is it a break even? The ideal gas law could tell us I think.
I don't have the skill to be on a knife's edge like that, where 1 psi might make or break a ride. My kind of janky riding can shine through almost any setup.
