Been on the hunt for pure darwins for awhile now. I know sustainable aquatics does a decent job of keeping things like their A. milii pure but I'm not sure if this applies to their darwins as well. I reached out to ibluewater mere minutes ago so we'll see what comes of that. My LFS gets "black and white ocellaris" from ORA, QM labs, and biota, but as far as I know/have seen these are nowhere near pure and some don't even turn fully black. Even if they did they still come with other problems like weird head/fin shapes + proportions.
