sRGB framebuffers

Hi guys, i’m back with another srgb question.

correct / wrong:

I want the screen image to be in the sRGB colorspace. In FreeGLUT i have to include the GLUT_SRGB flag, in LWJGL i was told to create this Display:

Display.create(new PixelFormat().withSRGB(true));

but i don’t notice changes.
glEnable/glDisable GL_FRAMEBUFFER_SRGB makes the image brighter/darker, but no as brighter as the correct image i posted before.

I don’t post code here, it’s too long: i’m asking you suggestions and hypotesis on what could be wrong. Thanks in advance

No idea. You could try to create an FBO and render to it instead.
