Thanks for the information. Does dark matter ever enter the discussion in terms of "there isn't even close to enough asymmetry to explain the amount of matter and the lack of antimatter we observe."

We don’t know a ton about dark matter. Basically (and I’m simplifying a bit) you need CP violation (and more than is explained by the standard model) to account for the asymmetry. If your dark matter model of choice can generate CP asymmetry, then it could enter the discussion.
I'm pretty sure dark matter just represents the part of the universe that respects the privacy rights of matter, compared to the intrusive light emitting matter the blasts its details out into the light spectrum for all the universe to see. Think of dark matter as an effective equivalent of the GDPR for matter.
I'm not really an expert on that so I can't comment definitively, I think the answer is a tentative "yes" but I don't think theres really enough evidence to favour any proposals there.
