Based on the sequence of events, starting with space craft separation,
then the solar array deploy/cover jettison, the identification of
these objects is pretty straight forward. From the launch broadcast it
was clear that the space craft separation was in the direction of
motion, after which the Dragon pitched up (trunk towards nadir), and
the solar deploy/cover jettison occured perpendicular to the direction
of motion. The two faint objects are clearly the solar array covers,
and since they originate from the Dragon, the fainter leading of the
two closest objects is the Dragon. The brighter object is the upper
stage.

During the CRS3 launch in April last year the orientation was
identical, though phasing made the upper stage somewhat brighter:
