I asked the same question about the high quality scans. Everything on the film was well within the dynamic range of the scanner. I wish there were some dots left, but I tried increasing the highlight contrast until all that was left was noise. The scans were high bit depth, not tweaked to look good on a DVD, not an MPEG-coded version, but recorded as they would be for movie intermediates. So, if there was anything on the film, it would be in the digital file and we would have been able to pull it out.

Since these were dupes, there is still the possibility that the dots were on the original, but it has never been found and probably doesn't exist.
