I thought it was pretty obvious that they were talking about sample rate and bit depth without using those terms so as not to confuse the layman, rather than compression of dynamic range. DVD audio allows for the sample rate to be increased to 48k, so BluRay might allow for that to be extended to 96k/24 bit. It still won't matter to the modern young consumer. There's a whole generation now who already think that music should be free. There's very little chance that they will now pay twice as much for it in a delivery format other than download, just for the sake of fidelity. Most of them don't even listen to whole songs anymore, they listen to their favourite 20 seconds of the song and then flip. Fidelity isn't high on their agenda, especially considering how much they would need to spend on a system to make listening to the 'improvements' a new experience.
