My images on iCloud are not updating on my Apple TV

I have a number of images in an album that I created on the iCloud website. On my Apple TV I am logged in to that same account and have the screen saver set to display the images from that folder. After setting it up from the Apple TV I was able to see the images in the folder. Today I updated the images in that folder and deleted a number of old images with the expectation that it would see the new images and then display those but it has been an hour since the update to the iCloud images and the Apple TV has not updated. Is there something I may have missed in the setup?
