First move to lossless CD quality.
If consumers don't have equipment (headphones/speakers, DAC) that can reproduce lossless material of good provenance with a reasonable degree of fidelity then it really doesn't matter how good the recording is or what bit depth/sampling rate it's recorded at. So let's get them to at least CD quality first, before worrying about anything else. I'm positive that even the best recordings are let down by shitty postprocessing work, lossy encodings, cheap DACs/resamplers and headphones.
Then we worry about whether or not HRA is of any use to anyone. Personally I'm of the belief that you can never have too much information, and yes, beauty is in the ear of the listener--so some people may simply never notice, honestly, and that doesn't have to be a bad thing.
