But, like you said ..... it may not be significant.

Not just the amount but the compressibility of the air in general. More due to the heat than the humidity though. That is one reason why turbos get intercoolers.
I saved us $120K a year just by bringing cooler outside air into the plant compressors at work (they used to just draw the air from around them). We see about a 10% to 15% decrease in their efficiency during the hot humid days in summer. Now, of course these are compressing way more air than any car does but the principle remains the same.
