It certainly would be welcome and I'd be interested to hear what it can do, but I wouldn't go as far as saying it was a games changer. The performance I can squeeze out of 16/44.1 is pretty good.
The few 24/192 files I have (from HD Tracks or Linn Records) can offer a touch more smoothness and refinement, but the difference isn't anywhere near what a good vs average recorded/mastered album will reveal. I wouldn't say I could identify a 24/192 etc just by hearing it, I'd say if it was good or not, the reason could by due to mastering rather than delivered bit rate etc.
If the delivery of higher rate files pushes up the mixing and mastering standards then it would still be worth it.
While record companies keep costs down and make a single "master" for all formats and markets then high quality kit is going to be held back due to the recording still needs to sound ok on a 20 quid portable.
What I've noticed in recent years more is "live" albums vs studio, I'm not talking big stadium stuff, just where a person or few has been in a small venue or recored live in studio. The studio, overlaid, dubbed etc stuff is so dead musically, the life, boogie and swing call it what you will is processed out of it..... Seems like there is no timing or connection between the musicians.
Play something recorded "live" and it rocks and sounds real.... or even some old recording from the 50's etc.... like an old Sun studio recording.... so alive....
