That's correct at least for PB301/360. I didn`t see FBReader sources from Pro series, but I think they remain the same.
The main reason behind using 4-color mode in FBreader is the speed. 8- or 16-color modes are much slower.

Image viewer uses best available mode so it doesn't needed to use so aggressive dithering. But there is no reason to use the same mode in the text reader.
I guess it is a matter of taste : some people will prefer speed, some others like me will prefer more beautiful images. But...
When I open an epub (I have converted my previous html file with Calibre) with Adobe Viewer in my 602, it doesn't seem to be slower than fbreader when displaying an image. And Adobe Viewer seems to use more colors, maybe 8 or 16 : the image is clearly smoother and more beautiful.
(The problem with Adobe Viewer is that it can't open html files...)

So maybe it would be nice to have a option for a 16-colors mode in fbreader, as it may not impact too much the speed (at least for the 60x/90x series). Do you think it would be very difficult to implement ?
