I saw the same thing. I watched the video and they seemed to choose the 4 primary pigments to be close to CMYK, but I was also surprised they didn't make a lookup table for other CMYK pigment alternatives. Seemed like it wouldn't be crazy to do and gives another nice artistic knob to turn. And if it didn't affect much, that would also be convincing that they weren't too sensitive to the 4 pigment selection which is also nice (Although, academic paper cherry picking aside, I was pleasantly surprised how visually close some of their examples were to the read world, for different pigments)
