That is awesome. All I got was just different images of noise when trying to decompress. :D I think i looked at thousands of them. The colors thing should be simple enough I think. Judging by yellow swapping to blue and vice versa, it would most likely mean that red and blue channels are swapped. Manually swapping them results in this: I'll try to tinker with it when I have some time. Awesome work, I'm excited.

Some good news some bad news. I played around a bit in kaitai and got it somewhat working for i2d bitmaps, but only for really small ones. Larger ones seem to be chunked, LZ compressed and run length encoded, and I wasn't able to figure out uncompressing them. The spec files mentioned above are gone for good I think, at least I wasn't able to find them anywhere (believe me , I tried). Not all is lost however, as the entire (?) Revenant source code is on github, so for someone who actually knows c++ it should be possibe to figure out the format.
