Does Arcore Pose getRotationQuaternion return rotation in real world coordinates?

I'm trying to get the pose of the device in real world coordinates (meters). I wanted to try inputting the pose of the camera as prior input to colmap for sparse point cloud reconstruction. The pose colmap estimates is not in any absolute measurement but an arbitrary value. So I need the rotation and translation quaternion from arcore so I could input it to colmap. Does the Arcore getRotationQuaternion return quaternion in real world coordinates? If no, Is there any other method to get it?
