That’s an interesting observation. I can see that being a possibility when they are very young (lots of leaf surface area, little wax, few roots), but over time I would think that would not hold true as the plants mature.
Something else I just thought of - might plants grown in a humid environment develop less of a waxy layer than ones grown drier? Seems logical, but I don’t know if that’s the case.
