I'm trying to have the custom artwork I apply to movies purchased on iTunes (applied through using 'Get Info' within iTunes 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 looking for the artwork to sync via iCloud, but I'm not sure iCloud can do this.

Is there any way to have the custom artwork apply to iPhone or iPad via iCloud? If so, how?
