Do Americans notice how someone learned English right away?

As a non-native English speaker, I’ve always been curious about this :) What are the biggest signs that someone learned English from different sources like movies/TV, gaming, school, language apps or everyday conversations?
Do native speakers actually pick up on these differences quickly when someone is speaking or writing, or does it all just blend together over time?

I’d love to hear your perspective.
