No, it was all in your mind. To repeat myself:

The higher the compression ratio, the higher the octane you need. You do not gain anything from running a higher octane fuel than necessary to prevent detonation. That's just a clever marketing gimmick the oil companies have been propagating for a while now. Either your car will detonate or it will not. Running anything higher than the required octane will simply cost you more money.
