No RGB limited option? (in Kodi settings)

If I set raspi gpu to RGB full my projector defaults to RGB full, too. As wtw and btb are clipped I assume player is set to RGB full as well. So full, full, full.
If I set raspi gpu to RGB lim my projector defaults to RGB lim, too. As wtw and btb are again clipped my assumption is that player is still in RGB full. So full, lim, lim.
I cant get the osmc player to display in lim, so I am not able to display wtw that way.
