Okay, to fit this definition of content previews for an app when hovering on that specific app as an ad: I like that my Apple TV does not show ads for apps I don't explicitly select in the UI, unlike almost every competing device which shows intrusive ads for unrelated stuff that I haven't selected in the UI, and may not even have installed or subscribed to. (I also like that it's the lowest latency streaming box.)

Apple TV is AFAIK the best device in its category.

I also think your definition is overly broad and doesn't reflect what an "ad" is. For example, if Apple cut the feature from iOS that allowed you to control your music from your lock screen, Spotify would also be willing to pay Apple to be able to control specifically Spotify from your lock screen. Does that mean "being able to control music from your lock screen" is an ad for Spotify? No. Does iOS allowing app-specific widgets on the homescreen count as ads, since if it didn't exist, companies would be willing to pay to be on people's homescreens? No, widgets are not by definition ads (even if some widgets may be ads!). Similarly, the Apple TV OS providing the ability for installed apps to show interactive app-specific UI on hover (i.e. the user has chosen to interact with this app, or has chosen it as their primary app in the OS), does not mean the OS itself has ads.
