PD-5ANS vs PD-6ANS

What is the difference between the PD-5ANS and PD-6ANS switches. Just starting to look at smart switches and I'm thinking of going with the Caseta. Also, is there a color change kit for the Caseta switches? Currently have Leviton ivory switches and not sure if I want to try to match or go with white in case the paint is changed.

The only difference is the capacity. 5amps vs 6amps. I believe the 5amp is being phased out.

The plastics are not field changable but most of the products are available in black, white, ivory and light almond.
