Seems the issue is with a recent Spotify update.

They changed their SMAPI presentation map, and removed the ArtworkSizeMap which is how apps find higher resolution versions, so the default low-res art is used.

For the curious the process is described here: https://developer.sonos.com/build/content-service-add-features/add-images/add-album-art/
