Vector 3 and Zwift

So I am new to the Zwift thing and I am wondering if there is a way to collect the cycling dynamics on a Zwift session.
Here is my setup:
Vector 3
Wahoo KICKR 18 with the KICKR using the V3 as the power source via ANT+
Zwift on Apple TV with the KICKR connecting to the Apple TV via Bluetooth.

The whole Zwift experience is pretty awesome if you ask me. Feels almost like being outside. When Zwift sends the ride to Garmin Connect I just get the power graph for the ride but nothing when it comes to cycling dynamic.
My main guesses is that Zwift itself doesn't support the cycling dynamics so there is nothing to sync back with Garmin... or the KICKR takes the V3 power and only reports that to Zwift for current power... or both.
