the bokeh chart was originally posted
in a dpr thread but comparative charts are gone. So I'm glad I databased copies for my research references etc- now shared here
The OP of that 2016 thread showed how the best transitions are smooth and pleasant, yet the "amount" of visible detail in the photograph is very shallow especially at shallow DOF in a wide-aperture image (DOF is extremely tight). The huge improvement is to design a portrait lens, which in some way extends the visible detail beyond the usual DOF.
"That is exactly what the 58G is doing!"
