Being pedantic, caching is a completely separate process and one in which AD is not involved. All artwork will be cached eventually, but by the GUI when the artwork is displayed and not by AD. The database that AD updates (though not for Extrafanart/Extrathumbs) is MyVideosXX, ie. the media library, and not the cache (which is Textures13.db). I'm assuming this is what you meant, but using the term "cache" is confusing as it has a somewhat specific use in Kodi.
