You are right, many of the topics are there. I thought about it again and my main point, at last, is only the "-punk" part of Cyberpunk. For me, it means some sort of rebellion against the system (e.g. runners against corporations, in most systems as Cyberpunk 2020 or Shadowrun). But here, the player characters do not rebel against the system, they are the system. Having this in mind, your ttRPG is still a good "high SF" one, and it has enough cyberpunk elements in the details to count as... cyberpunky? It is just not the main focus, in my eyes. This is political intrigue on the highest level.
