they can see encrypted traffic and that it is being sent to an IP associated with VPN services without too much difficulty, but they won't have granular control/access over your data/bandwidth. Meaning they won't be able to prioritize some of the sites/services you access over others because of the encryption. they need to throttle everything or nothing. And they won't be able to see any of your traffic or the sites you visit whatsoever.
