For single surfaces, here's the amplitude of the fresnel coefficients Basically exactly the same

Here's the phase, which are multiplied by a factor of -1

I don't think one is "more correct" in terms of creating a Jones pupil, so long as they are consistent. But as we see in #57 they do manifest as aberrations with different signs, so I do think the result ends up being physical.
