Extremely wrong. The difference between A=415 and A=440 is not "minute" at all; it's a full half-step difference! Also, no: absolute pitch does not necessarily confer the ability to distinguish very small differences in pitch. Many people with perfect pitch can name a given note if played, but can't reliably identify if the pitch in question is 5 or 10 cents off. This is a common misconception.
