This was because the display shader never did the correct color transformation. This is a risky fix as it expects all input texture to be in the correct colorspace (srgb). If they aren't this will produce darker result. If this is a huge issue we can introduce a global setting (like line width) to set if the attached texture is in srgb space or linear. This would avoid to change the drawing code all over the place. Pull Request: https://projects.blender.org/blender/blender/pulls/141237
