So far the earliest known release was 910206.

Once it's dumped then we can say the earliest known release is 910204.
If someone finds an earlier build then that becomes the earliest known release.
It may be bit rot or a manufacturing defect causing an incorrect date to be shown. It might be a location test or review sample. Whatever bugs are fixed may have already been found before 910204, but were taking too long to fix and there was a reason this board needed to be manufactured.
We may be missing a whole lot of builds, we struggle to get people to dump different revisions. The more builds there are, the less there are of each board and then the less likely they are to be dumped.
Without provenance and without a dump you can't really draw any conclusions.
