>it sounds more like what buyers today expect

Is that really true? Anybody buying music today instead of streaming is somebody who takes music more seriously than most. It seems likely they're going to care more about sound quality than the streaming audience.

Is it true? No idea. It's plausible. My point was that one example of a heavily compressed track doesn't make a loudness war. I offered a plausible alternative explanation of the same facts. It seems likely that someone buying a mass market album today would expect it to sound pretty similar across all formats.

I don't know why you've introduced this 'serious' vs. streaming thing.

What does taking music more seriously even mean here? If you seriously like listening to normalised Purple Rain on 128 kbps mp3 and also like collecting physical media, you might seriously like to buy and listen to normalised Purple Rain on your preferred (lossless, or less-lossy) format.
