I used the gpr_tools from here: https://github.com/gopro/gpr to create the PPM file from an GoPro Raw image.

Most likely because that "PPM" is still-mosaiced sensor dump, just out of gopro raw container.
It would be better to convert it to dng proper.

1. It opens fine in Gimp 2.10. (Just 2x green, but that's easy to fix.)
2. Yes the DNG works fine.

The Bayer CFA pattern is Red Green Green Blue, so if there is 2x green, if anything, that doesn't disprove my theory :)
