yes, what you wrote is true but there's more to it since we have a

Well, since we were talking about a tub, I was considering constant
total load. But you are right that the 6' beam deflection is still
greater than the 2' cantilever deflection, the constants in the
deflection equations are much less for the beam but not by a factor of
3^3 = 27.
