Not exactly. You are pretty much right on HDCD. If you have the HDCD decoder, you should get all the benefit with a normal DAC. What comes out of HDCD is 16 bit, not 24 bit. The extra processing sort of adds equivalent bits, but it's still 16 bit.

SACD cannot be ripped. This is a different way of digital encoding, unlike normal CD, it is Pulse Density Modulation, not Pulse Code Modulation. To the listener, the effect is more bits of resolution, but probably not 24. Anyway, it requires a special transport and decoder.

DVD-Audio has information that can be read on a regular DVD player. But the real high resolution content can only be read on a DVD-A capable player. A DVD-A player can play 2 channels with 192 kHz/24 bit, while a DVD-V player cannot. Similarly a DVD-A player can play six channels of 96/24, while a DVD-V player cannot.
