Their reported collision rate was against their CSAM hash database[1].

> In Apple’s tests against 100 million non-CSAM images, it encountered 3 false positives when compared against NCMEC’s database. In a separate test of 500,000 adult pornography images matched against NCMEC’s database, it found no false positives.

I don't follow the point you are making here. The goal of the algorithm is to match images so I would expect similar collision rates regardless of what image was matched against what set of hashes. The exact rate of collision will obviously vary slightly.

I think the point is that if Apple did optimize the algorithm using ImageNet then they and we are seeing the same best case scenario.
