GY4957 VS GX7811 (Ultraboost DNA CC_1)

Can anybody tell me what are the differences betwem these two types of shoes?
I know one had a black outsole while the other has white and blue. I also know the cage adidas logo is slightly a different color. The last thing i know is that the gx7811 model has light blue stitching alll around the upper while the other doesnt>

I actually own the GY4957 model, which i love so much. The reason i ove these so much is because of a cool feature it has that is rare to find on ultraboosts. When you wear these shoes out in the sun, the white boost midsole actually starts to shange color into a light blue color.

One last question, Does the GX7811 model have a color changing boost midsole, like the GY4957. have?
