I don't understand why they don't use 24/96 or 24/88 for Blu-rays.
In particular for music video concerts.
* Very few BDs are encoded at 24/96 (less than a fraction of 1%)!
** DVD-Audio used to be encoded at 24/96 for the multichannel audio,
and even at 24/192 for the Stereo track on some of them.
Now we are going backward, and people in the recording music business don't care anymore about audiophiles and the general higher fidelity of music reproduction. This world is driven by the dollar sign, and anything that is not streamed and of better sounding quality is prohibitively costly.
Just look at the prices of some LPs, and look at the decadence of hard physical software mediums like CDs, SACDs, DVD-Audios, DADs, ...
And they could have done a better job on the video portion of Adele.
