Hmmmm........ that's a new one on me.  Does this imply that an HD curve shot
with the same film and chemistry but two lenses, one uncoated and the other
multicoated, would have different shaped curves, CIs and/or speed points? If
so, how much?


Yes, the curve is flatter (more horizontal,) less contrast. Only tests with your own film, chemistry, and methods can show how much.
