QImageCapture photoresolutions do not correspond to still image resolution

Using the camera example ( https://doc.qt.io/qt-6/qtmultimedia-camera-example.html ) on a surface book, I can only select photo resolutions, which actually correspond to the video resolution, with a maximum of 3840x2160 (see attachment qt_res.jpg).

However, the hardware is capable to shot image with a resolution up to 3712*2784, which can be seen in the windows camera application (see attachment win_res.jpg )

Is it possible, that qt incorrectly parses the video resolution for the available still image resolutions? The combobox is filled with duplicate values, which correspond to the 15 & 30 fps video resolutions.
