He's right. You can see black bars to the left and right of the camera images. (NOT the bezel, but "light black", from it being the LCD)
You can also tell from the warning writing at the bottom. Notice that on the Aviator, the writing ends to the left side of the 360 view because the video is so tall, and the Explorer shows the text across the entire bottom.
I don't know if there is a setting that hasn't been set, or not, as I've never looked into it, but it certainly needs adjusted
