I don't know: one possibility is that either Linux or VLC/Cheese incorrectly detects the webcam resolution? Another possibility could be a marketing trick: an higher resolution is claimed through interpolation while actual optical resolution is lower.

I use VLC from Buster. the following is the rough english translation of my VLC that is in french.
- To set up the resolution of the webcam for a session and begin the session: Media>Open a capture device, then set up the capture mode to video camera, click on advanced options button and fill the width and height fields.
- To set up the default resolution of the webcam: Tools>Preferences, then click on display parameters: all, then input/codecs>access modules>v4l, fill the width and height fields
