Re: Does Melissa "Gloss Over" Image Noise ?

It's also not clear in what sense the RGB color readouts at low levels are "erroneous."

Because they (according to Adobe's Jeff Schewe) report tone-level values within Melissa RGB's linearized low-level region that do not accurately reflect ProPhoto RGB or Adobe RGB values ...

Just to be clear, Melissa RGB is ONLY used for the Histogram display and the color readouts...not you image preview display. The image preview goes from raw>ProPhoto RGB Linear>Display profile. The sRGB tone curve has no impact on your image preview display. So, the only impact of the sRGB tone curve would be color readouts in 0-100% (which don't relate to 0-255) and the way the levels are displayed on the histogram.
