I think this all ties back to listening habits. I find individuals who share this opinion are typically stream-primary listeners who mostly listen to playlists, singles, and generated "radio" stations (which is entirely valid! Not to mention that's the way most people listen to music, nowadays.)

However, there are nonetheless lots of people like myself that primarily listen to albums, maintain their own digital libraries, and use streaming platforms as a glorified "trial" platform for new music. I find those who tend to listen to music like I do really care about high resolution album art (and by extension the quality and accuracy of track metadata).

Frankly, since both needs are so widely different, I'm not sure there's any one solution for both. Goodness knows Apple Music tries, but to OP's point, it's clearly not succeeding in this effort.
