I don't think I have luma, I left the remaining steps
I'll leave it to the experts to confirm but from my understanding if you installed b9s then you WILL have luma even if you don't do the finalising step, otherwise the 3ds wouldn't start. You can confirm by holding select while switching it on.

Hey Guys, Can I update to 11.06 using luma 7.0.5 ?
If you haven't done so already follow https://3ds.guide/a9lh-to-b9s
Then you can update to 11.6
