What VaSA calls PF is actually called blooming, and is, as falconeye says, a non-issue nowdays.
It is my understanding that PF is caused by uncorrected IV/UV wavelenths of the lens and a capturing device which is sensitive to those wavelengths. If this is the case, then different IR filter and different CFA could emphasize PF on some cameras over others. On the other hand, maybe my hypothesis on this is wrong
Bokeh CA in my understanding is simply loCA and it manifests itself differently. Again, I may be wrong - actually, I am not sure if "bokeh CA" has even been properly defined anywhere.
