> It is fairly unusual for American not to Anglicise pronunciations

Anecdotal, but I think this is only true for French. For example, I think U.S. Americans (even those with no Latin American ethnic background) are much more likely to pronounce Spanish loanwords in a way that's closer to the original than Brits are.

If my anecdotal belief is correct, I suppose it's largely because of the very close contact between the U.K. and France on the one hand, and the U.S. and Latin America on the other.
