Yes, liquid water will not go above it's boiling point for a given atmospheric pressure. However, in terms of liquified gas in a canister, this statement is correct:
The higher above the boiling point in terms of temperature, the more vigorous the boil, and the greater the vapor pressure.

Mmmmmmmm . . . nope, not buying. The boiling point is a function of pressure, so as the pressure in the vessel goes up so does the boiling point. Boiling point is by definition the point at which vapor pressure equals atmospheric pressure. By definition "the higher above the boiling point in terms of temperature" with respect to a liquid in a canister, is a contradiction in terms. Until the canister fails, of course. It should read "the higher the temperature, the greater the vapor pressure". Has nothing to do with the vigor of the boil. That's a function of heat rate, not temperature of the fluid.
