Fuji had another channel recording backstage and K&C reactions from the skaters. It happened that they also put the videos on YT which were not geo-blocked. The videos include the speed map and the skaters were able to see that at K&C.

It's obviously Kaori skated with more parts in the orange-red color (higher average speed). But I also agree the speed sometimes should pair with the music which can be slow in tempo at parts (or obvious slowing down in the middle of the program when skaters need to take a breath).
On a side notes, it's funny to see the skaters reaction to their own performances at the K&C (it's funny she didn't want to see her own Lz, she knows it's problematic. And Wakaba on her flip too.)
