I was quite a bit wrong here regarding SCN\OFF. OFF does not mean compression is "off", but rather has something to do with offset for sub-images. I found a great source on the file formats here:

SCN/OFF format

The majority of the image files in The Incredible Machine, including the graphics for puzzle parts, contain an SCN and an OFF chunk. The image data is stored in the SCN chunk, while the OFF chunk contains an index for each sub-image's data inside the SCN chunk. The SCN chunk has its own compression format, described in the next section.
