I have tried turning on and off dither and every mode, srgb/absolute/relative. also with other icm profile. Is there something i dont know?

Does reducing the dither bit depth help?

Either way, to me it looks like the banding is inherent to the content and just exaggerated by the gamma calibration. Assuming your ICC profile contains an sRGB gamma calibration: do you get the same banding if you don't use novideo_srgb, but instead just load the VCGT curves of the ICC profile into the GPU using DisplayCAL (or its profile loader)?

When I enable calibrate gamma to (srgb,relative,absolute) the banding appear. It doesnt appear when I didnt set it. (Sorry I just been tinkering with it lately)
