Album artworks displayed in low quality (connected via BT to bmw car audio)

[kofas]

Hi, 

i have this weird problem that some of the album/song artworks are displayed in low quality (blurred images) but some of them are in normal quality. It's totally random which album/song has this issue. It happened to me last month before it was all good. Spotify is connected via bluetooth from iphone6s to bmw car audio (2013)

Any suggestions? Its really annoying.
