I don't know if Netflix has VPN blocking or not. but yes, the offerings do vary from country to country. I can use my same account in both the U.S. and MX, but my profile changes depending on where I am. Examples, off the top of my head: in MX, Netflix was showing Star Trek Discovery, which in the U.S. is a CBS All-Access exclusive; before the pandemic, they were showing recently - released movies (Spiderman Homecoming comes to mind) ; they were showing the John Wick movies in MX but not in the U.S....
