Comment (by mkver):

 Your command only sets the format (i.e. whole file) metadata title, but
 this seems to be ignored by the muxer. Instead the muxer writes per-stream
 metadata and that is also what the demuxer reports. To set it, you need to
 set stream metadata: -metadata:s title=somethingelse (see the
 documentation for how to set it for specific streams only). Not sure if
 this is a bug; probably not.
