That's because of the logarithmical response of the human eye. Maybe it would help if denoising tools and the encoder would also have the same logarithmical response to luma information (I don't know how the human eye responds to chroma levels). Has anyone ever tried redefining the definition of 'similar luma values' from something like |A-B| < C to Log(A/B) < Log C ?
