I am not familiar with the EBC pads, but looking at their website it appears it goes black, green, yellow & red. With black being closest to OEM and red being high performance. Looks like the green has 3 different models, the 7000 being their low dust version. The yellow has 2 models and sounds like they shipped you the SUV version.
Here is a "glimpse" at the green 7000 & yellow SUV pads side by side (taken from their website):
FYI, according to Summit's website, the green pads cost $106 vs $138 for the yellow. Not sure what you paid for eBay, but yellows seem to be better and more expensive. I'd probably install the yellows, but if you were dead set on the greens, return and get what you wanted. I believe the eBay seller tried to give you a free upgrade, but should have communicated if he didn't have the green pads you wanted before shipping them.
