Unlikely. There are likely two things going on:
First, as you say, the can with the loose cap is 'breathing' and water gets into
the gas.
Second, also because of the loose cap, the lighter components of the gas are
evaporating and escaping. The lighter components are there to evaporate faster n
the carb. and make starting easier. 'Winter' gas has more of these components,
BTW.
Dark colored cans also get hotter in the sun, which makes both these effects
worse.
