Purchase Protection on Pre-Owned Cameras?

A lot of credit cards have a clause against pre-owned items, but in the event of theft, are newly purchased pre-owned cameras covered? For example, an Amazon purchase of a “very good, like new” product, that would still have the valid receipt and everything. I’m asking specifically for Amex and Chase, but any use cases where this has worked for you would be nice to hear, too.

It isn’t for a repair, but for theft, which is why I don’t see used items in the case mattering when it comes to filing a claim. How would they have proof it was “pre owned” anyway?
