RE: Ineffective \override

Good stuff!  Ought to be referenced in the manual.  Or maybe appended
thereto.

Sure! In the latest 2.5.xx versions, you can do
  \displayMusic{\hideNotes},
However, it's easier to read the files where the macros are defined,
directly. See /usr/share/lilypond/2.4.x/ly/property-init.ly
or wherever the files are installed on your machine.
