I'd think it much fuss about ... nothing. Even if you believe the hype about IMD sensitivity of any quality driver, they're talking a target range of 25-30K where this occurs. I'd be surprised if even a minimal percentage of typical hi-res source has that sort of high end. CD-4 is the only source encoding I'm familiar with that regularly encounters that range, and that's just a control frequency that never makes it past the decoders.
Frequency range is just a small part of "hi-res" anyway. Full audible spectrum, yes, assUming that was available in the master. But mostly it's opening up the recording to provide cleaner, more accurate reproduction by giving the DACs more bits to play with. Regardless, I'd expect quality vinyl played on a high end system would give you higher frequencies.
IMHO, dbx encoding was (and still is) one of the cleanest compression schemes ever devised, and even that was limited to 30-15k on playback - not much better than a high end cassette really. The magic happened when the recording was decompressed with amazing amounts of headroom and an incredibly low noise floor.
