I think you're making this harder than it needs to be.First, no disc can be read at a higher resolution than it was recorded with. For the typical CD, this means 16/44. You can place this CD into a transport built by God and it still won't pull off more than 16/44. Period. That stream can then be sent to a DAC that will _upsample_ it to 24/96 (I leave it to others as to whether this improves the sound), in which case you need a 24/96 DAC to play it.
As for "true" 24/96 discs, any transport that can play them will pull off the 24/96 stream. It doesn't matter if this stream is sent to a DAC that then _downsamples_ it to 24/48 or something else, the fact is the stream was read at 24/96. Most of the 24/48 downsampling in these DACs is done for purposes of copyright protection, not because the DAC couldn't handle it.
Of course, if you put the 24/96 disc in a regular CD player it can't be read (well, assuming it doesn't also have a 16/44 stream). Why? It's a different format. Just because a DVD disc and a CD look the same, it doesn't mean they are.
As for why so many CDPs have 24-bit DACs, that's marketing and economics. This isn't new, 20-bit DACs were all the rage the last couple of years.
Finally, to answer your last question, your HK is going to read a 16/44 stream and send same. Your alleged player with 24/96 would read a 24/96 stream when playing a disc recorded as such (there is no such thing as a 20-bit disc). Would that alleged player _output_ the 24/96 stream? Maybe not, it may downsample it to 24/48 before output. For example, my Pioneer DV-626D has the option to output at 96KHz. But even if I use that option the manual says that for discs with copy protection the signal will still be digitally output at 48 (the analog output will be 96, however).
