SAP might deliver the profile names with the PFCG role data (AGR_PROFS), but they are not generated. You are just looking at the surface and that is all that SAP sends you.
You must copy the entire role SAP_xxx to your own namespace ZSAP_xxx for example. Then it (and it's generated profiles) are yours, based on the template delivered by SAP (as you chose to use it). When SAP upgrades the SAP roles again, you can compare your ZSAP to the new version of SAP role in transaction SUIM.
At least, that is the intended process... ;-)
