Would these kinds of misidentification account for some portion of dark matter, or are the mass measurements the same?

No, despite the headline their results overlap within the uncertainties of previous estimates of how much rocky material is in the Oort cloud.

Which is 0.1%-10% of the Oort cloud (this measure favours the high end, but it's one object). Still, let's say 10%.

The Oort cloud is ~0.01% the mass of the Sun

Stars are ~10% of ordinary matter.

Ordinary matter is ~10% of (Ordinary + Dark) matter.

So it falls ten million times short of what you'd need (as an order of magnitude estimate)
