I'm trying to have the custom artwork I apply to movies purchased on iTunes (applied through the 'Get Info' pane on a Mac) spread to my iPhone or iPad. As it is, these changes appear to just be local to the machine, so I'm stuck with the default artwork for iOS devices as they appear in the TV app.

I'm not sure if iCloud can do this sync.

Is there any way to have the custom artwork apply to iPhone or iPad?
