When optimizing image sampler settings, its not easy to see where the DMC Sampler was forced to keep the pixel “as is”. I suggest an option for “better visibility”. This means, if you have a range from 1 to 8 samples, 1 sample should be green, while 8 samples should be red.
Alternatively it would be already helpful if (instead of just many blue gradients) I could see red pixels where the sampler would have taken more pixels if available.
