Amazingly, the underlying display technology does not suffer from the usual CCFL-based artificially spikey SPDs. This, in itself, is an important difference, IMO. I don't think something similar could be done with the typical white LED-based displays such as the ACD24. As for which CMY filters, I don't see the absence of black as an issue because this is not dealing with the inherent deficiencies of inks on paper, I don't think that black is necessary in this case, as long as the addition of CMY yields a sufficiently deep and neutral combination. You see? But I'll admit not remembering all the details of the presentation. As for the conceptual superiority of this system, I would venture out to say that this offers, in my view, the potential for less metamerism than a traditional RGB emissive system since, for it is not trying to mimic the tristimulus values of a print system with a physical stimulus that has no relationship to the real thing since it is using spectral filters that closely espouses those of the real inks. To me, that's the real difference.
