the system account network services you mean? half of its rights are hard coded, the rest are given by user rights assignments.
so this would boil down to a matter of exactly what you want to check. network service, local service, service, localsystem, and system do not map back to everything the way a normal user account does. they are "system effects", meaning, a regular user context is unnecessary for them...if that makes sense.
