The first dip looks like white chocolate to me - tempered to give the mousse structure. The second is a napage or maybe just a caramel glaze. I think the first shake around is to make the sphere less perfect and more apple like.
ETA: The more I watch it, the second glaze is definitely not napage or gelatin-based glaze. The bubbles on the surface suggest something more rigid, but it can't be hot/warm caramelized sugar which is what it looks like. That layer has me stumped.
