Maybe I'm wrong but I don't think that adding colors to your diapers was done for DLs but just something that you correctly believed DLs would also be interested in. If you make diapers for ABDLs and incontinent folks buy them, they're still ABDL diapers. If you make them for the incontinent market and ABDLs buy them, they're not ABDL diapers, even though they might be great and much loved. It's not cute print defined but target market defined.
Northshore kind of blurs that line as you readily engage with the community. Based on what I know about the incontinence market (not a lot but a lot more than Joe Average), it could well be that the MegaMax is a DL diaper since we're typically the ones who love that kind of capacity. We wouldn't know without your intent being clear and that's probably not to your advantage in the market to sell it as a DL diaper.
