** You will not see any difference on a monitor or in a print, which have a smaller gamut than Prophoto RGB. Few monitors have a color depth greater than 8-bit, and most are 6-bit with dithering. Printers seem to fall between sRGB and Adobe RGB in gamut, but comparisons are complicated between RGB monitors and CMYK ink sets.**
