I disagree about the size & appearance. I wouldn't say this means the veggie would be more tasty. But I definitely agree on the taste part.
This is something I found in common between French and Japanese cuisine: Simplicity, but very good quality ingredients. (maybe this is why there's so many 3 Michelin stars in Japan)
In the US I would say it's hard to enjoy good French/Japanese for that reason. On the contrary, it's easier to enjoy the cuisines which relies more on spices, such as Indian cuisine, because those spices taste good everywhere.
