Yeah, you're right.
I just went and converted it with ADPro and made sure there was no dithering on or anything. Saved it 100% uncompressed as both BMP and PCX.
Files are here...
TheLook PCXTheLook BMPI tested both version to see how many colors they had (used a plug in I have for Photoshop) and both version say the same thing, 65 colors. Which is probably about right, really, for the actual picture. It's mostly all shades of one tan color.
