You shouldn't conclude too much from the bokeh fringing test in terms of contrast.
If the DoF is only a few mm the contrast is often very low. As also mentioned - the images were taken near the minimum focus distance of the lens.

   ... it's difficult not to conclude what you see with your own eyes ...... especially with expensive lenses .......
 I've just looked at several PZ 85mm F1.4 reviews and most look to have better contrast ..... maybe it is the close distance ....... but it just isn't inspiring!
