Happens all the time with monitors and dual sourcing of parts like panels where it is lottery on who has supplied. With the s22 the 'intl' and 'us' models have different model numbers. I'm more concerned when buying a car and trying to figure out in which country it has been assembled (quality and parts used can differ)

In the same market, maybe, but Samsung has U.S. versions of their products as do many other brands.
