No,
It is normal for a person to have superb mastery and recall of an area of study on which they spend considerable time and effort on an ongoing basis.
You can find an ornithologist who has a really amazing knowledge of birds too.

I think what a lot of people are noticing here is that this extraordinary ability has not been commensurate with extraordinary accomplishments and it leads them to downplay the significance...
The point others have raised about these people not having abilities in other areas goes beyond this "unique talent" "not transferring". The point is that the people with these "abilities" spend a fair portion of their waking hours maintaining them. The memories may be accurate but they're "honed", time is spent codifying them.
Most specifically, the memories are clearly very different anything "photographic".
Just consider, if a person actually a video tape of their entire life, using said tape to answer questions about "what happen on day X" would take a few hours of mental processing. These people answer such questions instantly.
They've made themselves "experts" on one subject, themselves, and the ability give instant answers on that subject is a clue to this...
You're making a huge pile of unsupported assertions, but this is the most egregious. You have the outline of an interesting theory, but little more. For one thing I see no evidence that there is any conscious effort made to maintain these memories, in many cases the people express every desire not to have this happen, yet it happens anyhow. At the point where your "making themselves experts" happens at a purely automatic level and against their conscious will you've stretched the words beyond any reasonable meaning, and I'm not sure your theory can even in principle be converted into something that corresponds to the real world.
