Amazing we have not heard from the "EZNEC Experts" with plots of a
metal vs. non-metal support ...

If the wires of the dipole are exactly perpendicular to the feedline,
and
no common mode currents, the plots should be the same.
The more sloping, the more coupling I would think, but even then,
it's rarely a problem.

Modelling the Inverted V without its support conductive mast is a little
like modelling it without a real model of its feedline, both ignore real
things that impact the antenna to some extent.
