I found an even easier, more reliable way:  Make sure the AppleTV is on.  Then with your Samsung remote, select the home/smart button, then scroll left to Source.   Click select or up, then scroll all the way to the right and select "Universal Remote".     On the Universal Remote screen, select "New Device" & hit select.  On Select Device Type, select "OTT Box/Game Console"; select "TV Directly" (if that's how it's connected).  For Select Brand, select Apple and hit select.   It'll then ask you to confirm whether the arrow keys work to control the Apple TV (you'll see a small preview of the apple tv screen).  Use the samsung remote to move to the up/down/left/right arrows and hit select -- you should see the appletv screen change accordingly.   It'll add the AppleTV to the samsung smart home screen with the correct logo, and the samsung remote will operate the appletv as well.   Good luck! ...
