I was asked by fellow member JadedSkywalker if the release is in Pan and Scan or in Open Matte. After some research, I can say that it is more than likely Pan and Scan, as seen from the shots below.

From the Open Matte screenshot, you can see that it has significantly more visual elements on the upper and lower parts of the shot. Even though it was ideal for an Open Matte release, I believe it is Pan and Scan.
