("Prominent" here meaning "writes popular books as well as academic ones".)
One of the things that jumps out is that "culture X" is rarely as broad as an entire country (except perhaps a microscopic one). There are always cultures within the country, defined by gender, age, religion, wealth, location, ethnic heritage, etc etc etc.
There genuinely are cultural groups who will speak less directly ("Would you mind passing the salt?") and those who will speak more directly ("Pass the salt.") It's not just more-and-less; you still have to hit the correct level for the specific instance.
Tannen is perhaps most famous for writing about the different styles that men and women use (in different groups; it's very much taught by culture, not biology). I found it immensely helpful for understanding not just what women say but also what I say. I highly recommend her books.
I'm sorry I don't have direct links to scholarly articles that provide exactly what you're looking for, but that's where I'd start looking for them. It's entirely possible that they exist -- but they almost certainly don't come down to "The Dutch are more direct."
