It's two different rooms. There's a Camera that's in the snowglobe room with that draws to a render texture, and it uses the Suspension script from the standard assets to copy the local transform from the "real" pickup magnifying glass in the main room. The camera's parent is scaled down and transformed so that the Camera lines up with what you would see in snowglobe.

The CameraTest world uses a different technique, where the Camera draws directly to your render buffer (clear set to none, no render texture). It works in stereo, but requires a bunch of tricks to render properly and copy the scale/rotation of your main VR camera.
