I think you got it the other way round.
At maximum aperture, for the non-WR DFA version, all the aperture blades would be retracted so there would be a round oof highlights.
As you use smaller apertures, the DFA oof highlights become progressively smaller and more distinct with the octagons becoming more obvious, not less.
The feel of the WR focusing ring when focusing manually is even better than the FA Limiteds.
