Macbook Pro Logicboard Replaced - How to know if replaced logic board is a new or used one?

I have a Macbook Pro 2016 model (Touchbar). Few days ago, I got a critical upgrade error and the mac wasn't starting. I went to the service center and they replaced the logicboard. My mac is running fine now. The serial number has been changed which i know is expected. My Question is - How do I know if the service center has inserted a new logicboard or just replaced it with some other unused Mac's logicboard on my machine? I checked the serial number on https://checkcoverage.apple.com/coverage and this is what it returns:

MacBook Pro (13-inch, 2017, Four Thunderbolt 3 Ports)
Purchase Date: August 2017
Serial Number: XXXXXXX

Coverage Expired

Does that mean the service center just used some 2017 model macbook and placed the logicboard on my laptop? What should https://checkcoverage.apple.com/coverage return for a new logicboard? Should I be expecting a Purchase Date: July 2023, since the repair was done this month?
