If someone stumbles upon this problem there is what we did:
After further investigation, we realised that ImageMagick is smart enough to automatically convert an image to grayscale if the image is an actual grayscale:
This will result in a grayscale if it detects only grey!!!
To avoid that, we are now using only RGB and use the parameters
-type truecolor -colorspace RGBfor JPG and-define png:bit-depth=8 -define png:color-type=6 -colorspace RGBfor PNG.@sayduck-daniel I merged a change for this to copy the single channel grayscale to the RGB channels: https://github.com/kcoley/gltf2usd/pull/98
