I also had the same problems - M240 profiles being too saturated. I've been asking Phase One / C1 on their forum and with a product request for support of the MD / 262 since the release of the MD. I raised the question again after the release of C1 10 and no support for the model. There is more info on this here along with the reply I received from Phase One / C1 :
After receiving a reply from C1, I contacted Leica to ask the same question. Last week I received a reply from Leica.
"Your mail caused us to revise the capture one support of Leica cameras together with Phase One. We have started the dialogue to include more models, and I expect to see the integration of M (Typ 262) and M (Typ 246) pretty soon."
So fingers crossed we may see more M support in C1 very soon.
