Netflix streaming with American account?

A well-known from America has recently created a Netflix account. If I use the same account in Switzerland, will there still only be displayed series that are available in Switzerland?

Yes, go to IP.

I advise caution. Netflix has recently announced that they are now actively targeting people who share their account with others who do not live in the same household.

Yes. This has copyright reasons. I notice that when I open Netflix in Hungary, in Austria or in Germany, that different content is different, and if they exist, the languages available are different.
