I don't see any major issues related to bokeh or contrast from these images.
It may not show in carefully arranged and selected official glossy marketing materials ... but it will rear its ugly head in real life - exactly in those situations, when owners of the lens are already most challenged to capture good images.
There is an issue! Otherwise Nikon would never have admitted to it up front and included warning language and images in their 300/4 phase fresnel "brochures" and added (only partially effective) correction functionality to nikon software ...
Those images were from a production unit that someone purchased in Australia.
