I think I've found a bug (when using a Canon 9000f MK2), scanning at 16 bits color (AKA "Color") produces an apparent proper image gamma of 2.2, while choosing to scan at "48 bits color" produces an image too dark, or an image having an approximate gamma of less than or equal to one.
Both scanimage and xsane, as well as enabling and disabling Color Managment exhibit this problem. A temporary work around when scanning at "48 bits color", would be to open the scanned image within Gimp, opening Levels and moving the middle slider on the first slider to a value of 2.2. (Hence, first selecting Auto Level, then adjusting the gamma to 2.2.)
