Notes
The duplicate resolutions are shown because the camera is reporting different color space for each resolution. Where these use common popular color spaces then these names are displayed. If the camera has some proprietary color space it does not return a color space name. If the
camera retuned the same resolution with the same color space then these names are indexed.
