It's a bit hard to know exactly what he means, but a "rich black" is a specific color, so that is going to be addressed in a DLP. Assuming he's not talking about that but rather the black point of the profile,  he may really mean allowing more chroma as a tradeoff for getting a darker black. i1P won't allow you to specify the precise composition of the profile black point (unless I missed it somewhere). Profilemaker did, and CoPrA does.

> Hi Dan. Nothing could be easier to change than TAC in i1P: In Profile Settings there is a slider for it. To preserve a specific build for a rich black you would need to make a device link with that rule.
