It certainly is a SAP role if it's name starts with SAP. They are updated at will by SAP as templates and are always sent without profiles. If a SAP role has a profile, then the customer must have generated it.
Via the change documents for roles you can find out who changed the value and generated the profile - but that does not really matter much, as you should not use them in the first place for this exact reason that SAP must have a way to send template updates to customers.
Another reason why you should not use them is because from a qualitative perspective they are often terrible (I think that is fair to say with a straight face even here on SAP's own website... :-)
