    Maybe this review gives you an answer?
    As far as I understand, the Ultra basically uses larger area on sensor to produce video with even more wider FOV.
    The sensor has 4:3 aspect ratio, but video uses only part of the sensor's height for 16:9 aspect ratio. Ultra uses more of it, and causes video to be compressed vertically (recorded at 4:3, but converted into 16:9), that creates even wider look.
    Full sensor area has 4000x3000 pixels, 4K video has 3840x2160 pixels. 4K Ultra records 4000x3000 pixels, instead of 3840x2160 pixels, and converts this to 3840x2160 pixels.

    Disable gyro and distortion correction. Now you have wider FOV when ultra is selected.

    But when you do that, you get un-stabilized (jerky) picture with annoying distortion, don't you?
