It's only a matter of time before physical discs are rendered obsolete.
First problem is that you cant generalize "streaming is better than BD" or the other way around.
Second, while it might be the case that 4K streaming is equal or better than BD its not like every movie is available at that resolution.
To give a small overview:
BD trumps every streaming or download service that offers 1080p.
BD might be inferior to 2160p streams (didn't really test that enough) but then the sound part comes into play (which you mentioned), not to mention the availability.
UHD BD trumps everything that streaming or download services are offering in 2160p (only exception might be Kaleidescape as I think that they are creating their own versions from the studio's master).
In many cases there is no BD of a TV show so that streaming or download services are offering a significant increase in picture quality. Amazon offers still the best quality when compared to iTunes or Netflix.
So the only real alternative to BD is the already mentioned Kaleidescape and its Kstore.
