Question Getting the correct cameras transform using a path

This is using a tracked dolly path camera

if I go Cam = Main Camera
print(Cam.name + " " + Cam.transform.position );

then Cam.transform.position has no relation to its actual value,
I know this to be true based on where the camera is in the world and the value in the cameras inspection transform

so how do I get the true camera transform?

 

The thing is its not valid last frame either, the results from Cam.transform.position are nowhere near where the camera was, it was 100s of units away. Almost like it was a different camera, but it was the same camera. checked it by printing out its name before it prints out its position.
Even when I froze the camera path update so the camera stays in the same place, Cam.transform.position still was changing around.
I spent hours on it, tried everything. In the end I wrote my own camera path spline tracking which uses the paths generated from cinemachine, my interpolation is not perfect but its good enough.

 

Yes I thought that could be happening, thats why I gave the camera a name like 'camera gCXgsd6' and printed out its transform.position and name together in the console to make sure it was the same camera.
