Where's the sophistication? It's mostly vegetables.
I find a lot of sophistication in Italian cooking, especially accompanied by a good wine. The problem is that in the US Italian food is mostly some fastfood abomination that is not really what is eaten in Italy.
You can find sophistication in ramen too. But Italian cuisine revolves mostly around very simple dishes with little preparations (including the most famous pasta or pizza) and in our every day life we eat lots of vegetables, often raw.
Other cuisines in Europe are generally require way more steps/preparations/ingredients.
Risotto is even harder for various reasons. And what about Sartù di riso?
But that doesn't make dishes or a cuisine sophisticated per se.
To me sophistication requires knowledge and mastery even if you need to make a very basic and the result is not good, think of a beef Welligton or roast beef or a soup d'onion.
Those are all much more complex dishes than making a pizza, they require more work, more ingredients, more time, more preparations.
One of the most refined food I know is classic French omlette with just two ingredients, eggs and butter.
I don't say the Japanese lack refinement (sushi is one example of this), still there are a lot of complex Italian dishes as well.
