That depends on the countries and on whether the Jews were orthodox or Reform. In Germany, for example, the majority of Jews were NOT orthodox and dressed very inconspicuously - as in many other countries.
In South Africa, like most countries aside from the USA and the UK, the Jewish communities are overwhelmingly Orthodox. Whether or not a person who attends an Orthodox Synagogue is Orthodox in his "non-synagogue activities" is purely up to the believer. So, some members of the Orthodox community may not actually be observant Jews and would appear like Reform Jews in the USA. However, they would not call themselves Orthodox, but Jews who happen to belong to an Orthodox synagogue. Actual Orthodox Jews in South Africa would be indistinguishable from Orthodox Jews in the USA.
