I believe one of those rear calipers has an electronic park brake actuator as well. Having that standard rear caliper and bracket painted to match would drive a few additional part numbers into the assembly plant. It'd likely drive up the cost as well, and be somewhat prohibitive for a system that provides marginal benefit to the customer for the cost. The standard SS rear system uses different caliper (Brembo), rotor hoses and function of the park brake. Although the SS parts technically fit, using them on an LT would introduce option proliferation and build complexity during assembly. At some point the decision was likely made that a full upgrade on an LT to an SS system was not economically sustainable.
The LT opgrade option that the OP ordered does include 4 piston Brembos, however they are not the same as the SS Brembos. They are a smaller version that use a 12.6" rotor (a different, thicker rotor than the base LT 12.6" rotor). The SS standard front rotor is 13.6" diameter with a beefier 4 piston caliper. The LT's Brembo caliper design is common with the Cadillac ATS, and I presume it is intended to have desired clearance to smaller wheels offered on LTs and ATSs that aren't available on SSs.
I'd look into a caliper paint kit if you want the rears to match.

I get that it's a cost/compatibility issue. But if Chevy is going to go to the trouble of offering an upgraded red caliper for the front it should have at least color matched the rear single piston caliper or not offer the option at all. Seems like a half ass way of doing things the way it is. I wouldn't be happy if I paid $595 for the red caliper option and only got red front calipers.
