Audio channel infolabels not precise

Like mentioned here, it's been bugging me a while already that the audio channel infolabels available to skinners only return a fixed set of values not representing whether there's a LFE channel e.g. (5.1, 7.1) - you only get the total number of channels which isn't very helpful. Some layouts even seem to be missing altogether: 3.0 e.g. which is a rare, but an existing channel layout for jazz releases.

Currently, skinners can only either use labels like Mono, Stereo and Surround or guess which layouts are the most common. This is not precise in any way or even misleading - e.g. if 5 channels are interpreted as 4.1 although the file has a 5.0 layout. On the other hand, Kodi seems to have these information at its disposal e.g. in the OSD audio settings dialog where the currently played audio codec with the correct audio channel layout is shown. I'm aware that these information are only available during playback atm. But not even the player infolabels for audio channels return precise audio channel layout information.

Can this information be made available via the DB as a more precise infolabel outside the audio/video player? It would be great to be able to show more precise audio channel layout information to users with Kodi v19.
