For users with limits on mobile bandwidth, it could be important to know the codec and /or bit-depth of the currently playing track. For example when any tracks which cached when I started playing on Wi-Fi (ALAC in my situation) before getting in the car have been exhausted and it switches to streaming (OPUS) I’d like to be able to see that so I can choose whether or not to continue playing. The codec info shows in iOS but not on Carplay, and it’s illegal in my region to look at a mobile phone while driving.
