I ran every image in the graphic library through a custom script in Paint Shop Pro. Basically the script took the original, reduced it down to a lower color pallet than what the remote could display (32K colors) with "error diffusion" enabled.
Basically they are just dithered images at a much lower color pallet. I recorded the changes I made to one image and saved the script, then applied it to every image in the folder and produced a second folder with the altered images.
The problem was, I had to go back and replace every image in the original template file one by one, page by page. It took a couple hours, but I did this for for the T2-Cs, T2x and KX2 as they all have similar color capabilities.
You can see the effect, but only when zoomed in about 400%
