Kodi detect DV by dovi sidedata or if the pid is 0x1015, blue ray. If the media does not equal any of it dual layer is not used.
Only the part of the result of ffprobe Input #0 is data need to detect DV dual stream.
Just run ffprobe on your media and it will show the streams and if there is sidedata included or not.
If not demux it and remux again!?
