My Question or Issue

So i saw my friend's screenshot of her playing a song on Spotify called Beautiful goodbye by CHEN with a fullscreen Artwork so i went to check myself if mine any different. turns out it is. so to prove it I went into my first ever Spotify account with Free Plan (and never once subscribed to any of Spotify's plans) to check the song I know would play an animation artwork when the song is being played, screenshoted and went back to my main/current Spotify account with Family Plan (of 12 Months) and the results are true. it has a different artwork. Tbh i like the free plan artwork waaay more than the premium plan. and why is that? why is it different from e.o? and I also checked the latest update at Google Play Store (it's the latest). So please kindly explain.
