Exact steps for others to reproduce the error
[No matter if you have JPG, PNG, TGA when you use a Gamma, RGB Curve, Color Ramp the image get stepped like the image is not process as 16 bit floats, even If I change this value the image still in the same way stepped, one time in Substance Designer happened to me this I reported and the told me to change it to 16 bits float and that was all, but in blender when I change this nothing happens.]
[Based on the default startup or an attached .blend file (as simple as possible)]
