Is that the case in the whole EU? Because my AmEx gives me 1% cashback here in the UK, and that's been true since long before Brexit.

Non-partner Amex's are considered "three party card schemes", and therefore not subject to the interchange caps [1].

This means that there's a chance your merchant has been paying more for each Amex payment.
