 From captures of the traffic between an iOS device running iOS 12.2 and an AppleTV running tvOS 12.2.1, one can see that the communication on the main mirroring HTTP connection is encrypted once the handshake is completed. This could theoretically be part of the new AirPlay 2 protocol. The AppleTV running tvOS 12.2.1 identifies as AirTunes/380.20.1.
-When connecting from the same iOS device to an AppleTV 3rd generation (reporting as AirTunes/220.68), the communication is still visible in plain. From the log messages that the iOS device produces when connected to an AppleTV 3rd generation, it becomes apparent that the iOS device is treating this plain protocol as the legacy protocol (as originally introduced with iOS 9). Further research showed that at the moment, all available third-party AirPlay mirroring receivers (servers) are using this legacy protocol. Given Apple considers this a legacy protocol, it can be expected to be removed entirely in the future. This means that all third-party AirPlay receivers will have to be updated to the new (fully encrypted) protocol at some point.
