It's an old thread, but I found a solution. The game is using a Chroma Subsampling technique, similar to the one in keijiro ChromaPack unity plugin. Luma is stored in Red channel of the image, Cr and Cb are stored in R and B channels of the compressed image to the side. I wrote a python script that can extract the images from the asset files. Hope this helps, if anyone's still looking into it ^^
