It isn't possible (or legal) to change the IMEI number so if it matches your box, it must be the same phone.

Why would they do that and risk serious prosecution?
Serial number could be changed legitimately if new parts are no longer compatible with original system parts. For example the new screen may have required an additional new component that meant the original serial number would not have provided the correct information when checked in future for service parts.

I honestly wouldn't be concerned though @K8ighty3
The IMEI is the unique identifier. The serial number is fairly irrelevant.
