What you're highlighting is the lack of avalanche effect with perceptual hashes (on purpose). This makes them great for identifying transformed content (e.g. local TV channels via a cable box, ads on channels with slid in lower third tickets, etc) but horrible as an evidentiary basis.
That said, there's no need to clickbait here. Perceptual hashes are going to be a hot topic for a while here.
