Apple TV displays incorrect square artwork for some TV Shows

Hello,

Is there a reason why some TV Shows within the Apple TV still show an awkward square picture of the show inside the 2:3 frame whilst others show the correct 2:3 artwork? It looks very ugly. All movies look perfect and all have 2:3 format.

When I do a search for a TV Show I already have I can see that a 2:3 poster is there so why can’t that be used instead?

Any ideas?

cheers!
