Before theorizing on this lens, I would urge everyone to see the below image set from this lens.
This lens has about the creamiest bokeh of any normal lens. It is absolute butter. And like all N coated Nikkors, color/contrast is extremely high, something that these kinds of “tests” don’t always tell you.
Clearly for professionals wedding shooters, portraitists, and general shooting, this lens is a no-brainer.
Anyway, in case you haven’t seen these, have a look at this set of 58 f/1.4G images from Joe Marquez that he made in Hawaii. Lots of wide open portraits made in this set, and they look terrific.
