SDL 2.0.3 vs git/hg HEAD colors are much darker?

Can anyone explain this?

Top one is using SDL git mirror repo.
Bottom one is using SDL 2.0.3.
This is run on the same machine, windows 7.

I don't see any commits that have to do with color/brightness/gamma from the release of 2.0.3 to hg/git HEAD of b577c4753421, so, what could explain why 2.0.3 is so much darker than the git/hg repo?

Also note, they were both run in a window, not full screen, and I am not using any special calls like SDL_SetWindowBrightness() / SDL_GetWindowBrightness() / SDL_SetWindowGammaRamp() / SDL_GetWindowGammaRamp() / SDL_CalculateGammaRamp().

Platform/renderer backend? First thing coming to mind is the ImageIO
gamma fix on OSX, although I don't remember when exactly was that
committed.

Using openGL directly, SDL 2 just sets up the window.
No SDL calls to draw anything.

Are you using SDL_Image when loading textures?

Nope, nothing SDL related to load textures.
SDL only handles input & screen setup, nothing else.
