That is indeed much more compact than we see here up north. This Agave potatorum Kichijokan/Kichiokan/Kissho Kan Variegata grew up with by far not enough light and hard calcium rich water. Quit a different form!
Just to illustrate, I added a pic of A. potatorum var. verschaffelti I photographed in Stockholm (Sweden) botanical garden. Look how much more the leaves are standing apart, lacking UV, nothing like your (beautiful) compact plant at all.
