FYI the first time About This Mac is opened - whether that be because it's a brand new Mac or because macOS has been reinstalled - it will query an Apple server with the last four digits of your serial number and return the exact model name. If you're not connected to the internet it will just say "MacBook" or "MacBook Pro" etc. until it can connect.
