What is the use of other modes in AVAudioSession, when default mode is compatible for all categories?

// Access the shared, singleton audio session instance
let session = AVAudioSession.sharedInstance()
do {
    // Configure the audio session for movie playback
    try session.setCategory(AVAudioSessionCategoryPlayback,
                            mode: AVAudioSessionModeMoviePlayback,
                            options: [])
} catch let error as NSError {
    print("Failed to set the audio session category and mode: \(error.localizedDescription)")
}

Unable to understand the use of modes in audio sessions.

The other modes are optimized for specific usages. "Compatible" is not the same as "best." For example, when using the video chat mode:

the device’s tonal equalization is optimized for voice and the set of allowable audio routes is reduced to only those appropriate for video chat.
