Kozu had a different helmet in DOTD (between seasons 6 and 7) because it was Kozu's ghost possessing a statue of Kozu. The second GSW first appeared in season 4. Both the first GSW and Kozu originally appeared in Season 2, so there would have been no reason to recolor the helmet just because 2 seasons had passed. Also, how should they have gotten the stone warrior out of the sinkhole? They are clearly different stone warriors.

Their armors have different colors, as well.
