GdkPixbufs are always in the 8 bits-per-channel RGB or RGBA formats (you can check the presence of alpha with gdk_pixbuf_get_has_alpha()) so there is no other information to get. If the image is in a different format it is converted upon loading. (There are some provisions for different data formats, but the only really possible is the described one). If you need to query/manipulate the original images, you can either use particular libraries (libpng, libjpeg, libtiff, ...) or use a general image manipulation library (there are several but I cannot recommend any so I will refrain).
