Center Cap variants, 2007-2009 and 2010-2014

So it’s my understanding that Cadillac used several variants of the center on the 22” wheels. Seems 2007 and 2008 they were the ones with the seven rectangular dimples and crest was all chrome. The 2009 they continued to use the rectangular dimples but went to colored crest. In 2010 they changed to a slightly different cap to go with the new wheel part number. These had gum drop dimples at the edge. Those only came multi colored. But on my car I have these. But it lacks red....the other side it has red and all the other colors. What gives is that for a special edition or did the red fade perfectly?
