I think it really boils down to "the details are significant". It's
not really the signature packet that is relevant, but the actual
signature (i.e. number generated using private key). This signature
definitely uses a hash. We know that hash varies between data sigs and
certs. So here's the question:

Does the (mathematical) signature differ between data sigs and certs
in any way besides the varying hash?
