I’ve never heard someone refer to a European dish as having umami, it’s just upper class people showing how cultured they are by knowing the Japanese word for savory flavor. To top it off it only gets used when talking about the big three Asian countries. No one is talking about the umami profile of Vietnamese food. It’s the same kind of Anglo person who would read Sun Tzu while drinking lapsang souchong in the mid 20th century. Both are fine things, but together you know this guy is sad about the fall of the British Empire.
It has become common to use umami alongside sweet, salty, sour and bitter for all kinds of cuisines in German. That's a recent development, it has only become widespread during the last 10 years or so, while being almost completely unknown before that, but now it's semi-officially the "fifth flavor" and commonly used to describe a Thuringian bratwurst just as well as a Japanese soy sauce.
