Where I've seen this discussed, most people seem to agree with you - that they don't personally feel any difference.
However, I personally feel a huge difference in how I perceive the world - in the three-ish languages I know, but I also feel some differences in regional variations of British English.
It's for this reason I feel fascinated by language and saddened that people seem to be converging on English as a lingua franca.
