Now let us have a look at a more problematic situation. More precisely, what happens with fine detail when you apply this technique. I have created an image with small, little details in white, while the rest of the texture is black. I am not a graphics artist (duh), but you can imagine using a real texture with small details in it. With this, the final conclusion will be the same. Again, the top image is an original 24-bit image, the one below that is the ordered dithered version, and the 3 below that are the filtered versions (those that try to show off 22 bit color).

In the images above, it is already very obvious that the original and normal dithered image are very similar. The filtered, so-called 22-bit images, however, look a bit washed out. Again lets zoom in to see what happens.

 

These zoomed images clearly show what happens: all detail is smeared out and the intensity is reduced. This is a typical result of filtering. The spatial resolution is being reduced. Up to now, we can conclude that the filtering technique does provide better color resolution (proven by the previous series of images), but at the cost of the spatial resolution, as small details are removed or smeared out. As a result, images shown using this technique will have a fuzzy, blurred look.
