Yeah, it will be completely different  fingerprint  when you add a passphrase to SEED.  Passport HW is also capable to show master fingeprint ,  and this feature is very useful at checking  if  password you have entered is correct. If you see on display that some  characters differ from those that relevant to your SEED+password it means you have entered the wrong password, forcing you to enter correct one and, thus, protecting your nerves at checking balance on wrong wallet.
