As an update to the earlier question, as of 09/2018 this is available on the Square D (Schneider Electric) web site. Purple is now the combination GFCI/AFCI breaker test button. White is AFCI only. I think that current GFCI only breaker has a yellow test button (such as would be found in a garage) Several homes I have inspected lately have all purple combo AFCI/GFCI buttons even for places that only require GFCI - probably just easier to purchase and install all of the same model.
What color are the test buttons on the QO and HOM AFI, CAFI, GFI, DF and EPD breakers?
