I was not explicit enough, okay. I was not so worried about the case where only 10 bytes changed. If you insert a single dot in a jpg image, chances are that your binary content will change _a lot_.

So, no problem deducing from 10 bytes changed that it was a minor change. But you cannot deduce the opposite of a 1MB change!
