Apple Music Artwork on iPhone 14 Pro Doesn't Match Desktop

I haven't found a community forum solution that works for me, nor elsewhere. And a lot of answers are confusing. So, trying again with a new post.

Within Apple Music on my iPhone, much of the album artwork does not match the 'correct' artwork attached to the albums. Everything is correct in desktop. How do I fix??

Notes:

• iPhone running iOS 16.1.1 currently. Pretty sure problem existed in earlier versions...
• iPhone 14 Pro. Pretty sure I didn't see this problem on my earlier iPhone XS
• I have 24.35 GB of manually-synced music on the iPhone. I see the problem with much of the music, but not all.
• Problem affects music bought through Apple Music app (desktop) and music uploaded, indiscriminately - I think
• Apple Music app viewed through desktop is 100% correct. So, why does the artwork not sync correctly when iphone is plugged into laptop and I manually sync...?
• I've already signed out and in of Apple ID, on iPhone. No luck

Any thoughts, forum?
