Probably, due to headless LDView for Linux uses OSMesa, while Linux GUI version uses Mesa, and LDView GUI version for Windows might be uses some other OpenGL implementation.
OSMesa is a bit different from Mesa: https://docs.mesa3d.org/osmesa.html
So, headless LDView for Linux with OSMesa does not have a colors handling bug.
