Is there a way in scheme to say “is this grob being typeset because of an explicit command (\clef bass), or implicitly (because of a line break)”?

 

To highlight based on an "explicit command" you will need to analyze and alter the music _expression_.

Learn something new every day...

 #(define highlight

   (lambda (grob)

       (if (boolean? (ly:grob-property grob 'non-default))

           red

           black))))
