Detect when a tvOS top shelf tile/slide transition occurs?

Our tvOS app makes use of top shelf Carousel style slides to promote our content.

We would like to detect when tvOS transitions between individual top shelf slides, regardless of whether the slide transition is made by a user (via the Siri remote), or by the system idle auto-transition.

Has anyone achieved this, maybe there are undocumented system hooks or events we can listen to?
