I do not entirely agree. That is probably the case for many cars; BUT thinner air allows the throttle plate farther open which reduces manifld vacuum which decreases pumping losses. However some ECU's counter with more fuels so . . . . .
I "think" I've read that there is an optimal temperature for gasoline evaporation, MIGHT be related to that . . . .
Heating WVO for a diesel is simply a matter of making it flow through the lines and the pump. Gasoline already flows pretty darn well.
