This video shows the OZ display during an ILS 09 approach to KTNT (Dade Collier Transition & Training) in Miami.  The localizer is a vertical blue line and the glide slope is a row of X's.  The open green circles are the outer and middle markers and the filled circle(s) is the runway.

Note that the localizer line initially dark blue turns light blue when the localizer is alive.  The heading bug is a set of heavy moving green boxes.  The altitude bug is a set of horizontal boxes which are light blue when the aircraft is below the target altitude and brown when it is above.
