You'd be wrong. Imager can write to bmp, png, tif, ico at 4 bits per pixel, though png was only added to that list in Imager 0.90 (April 2012). GIF is a special case - if the stored palette is 4 bits (16 colors) then it will start compression with a 5 bit code size, there's none of the packing 2 indices per byte as for the other formats.
