Maybe im wrong on the colour thing, this site shows a blue lined cable at the bottom. but that could just be an error.
My X1 also had the bronze painted cable.
But the strange thing is the sound....Unfortunately i sold my X1 so i cant compare to the 007S now.
If you have both, are you able to switch the cables and try?
I am going by the following:
1) I swapped X1 and L500mk2 cables and it was 100% sure , the L500 cable brought out a bit more in the upper trebles, and was a hint less bright
2) X1 is not present. but swapped 007S and L500mk2 cables onto the 007S, and the L500 cable was significantly less bright up top. Anecdotally there was an 007S X9000 owner in USA who swapped their cables and found they sounded the same.
