The 24/96 Pure Audio is the blu-ray disc. That resolution won't fit on a redbook layer. Actually, it's DTS-HD 2.0. I have two of these blu-ray discs, Solit Ring and the Mehta Turondot. Both of these surpass their original releases in sound quality. Having an entire opera on one disc, easily searchable, is amazing. Seeing more discs like this would be nice, but I don't think they've really taken off. Maybe they should try releasing something new on these formats instead of retreading the same ground over and over again.
