You mentioned that you couldn't feel any difference on the stone with your finger (and they are assumed to be flat) but that it sounds different with the blade. Wouldn't this also be the case if your stroke wasn't even? Especially if you're applying any pressure. You probably set up the same everytime (how you hold it, how you sit positioned to the stone, etc) so your stroke is probably consistent and repeatable but it may not be even through the pass. You could be pressing or lifting on the heel, apply more or less pressure at some point in the stroke, etc?. and that would result in a different sound?
