Warning, I am also a layman, but I don't think we know how clumped dark matter is. We know it has to be spread out on galactic scales, but that doesn't mean it's spread out at solar system scales. Some people even suggest dark matter could be black holes with intermediate masses. If we can figure out how concentrated or spread out dark matter is at the solar system level, it constrains the models that would fit the new data.
