A large enough sample of Europeans speaking English. Many of them are easily distinguished with a bit of practice. This guy is definitely Dutch.
It's definitely Dutch
"Generic Euro"? I'm not sure where you're from but I'm German and I can't think of any European accent I'd consider "generic Euro". There are a few accents (e.g. Dutch/Swedish/Danish/Norwegian, German/Austrian/Swiss, Spanish/Portuguese) that sound similar to each other to me but they're generally still in distinct clusters.
