Change Apple TV User photo
So I have a separate iCloud account and iTunes account. When I set up my User on Apple TV, my name always comes up twice, one linked to iCloud, the other to iTunes. I remove the iCloud one because there's no iTunes media linked with it. The iCloud one has my Profile Picture from iCloud, but the iTunes one doesn't have a photo. I'm not sure how to add a Profile Picture to my iTunes account to have it show up on the Apple TV. Anyone have any suggestions? Thanks.
Apple TV 4K, tvOS 13
