Hello, Has anyone dissected the AdobeRGB profile, or knows what it actually contains? The reason I'm asking: I have the Samsung XL20 display, which covers some 113% of AdobeRGB, so I usually just work in this color space. XL20 offers the option to calibrate 4 profiles and save them directly into the display: one profile covers the whole gamut of the display (for massochists who love overly deep reds), the others are sRGB, Adobe RGB and 'emulation'. In emulation mode one can store any color space with a smaller gamut (say, of a printer or another display). It's also possible to specify the parameters manually (green, red, blue, white and black point, gamma, luminosity) - see screenshot so you know how it works. I figured I just save the AdobeRGB profile in both the dedicated AdobeRGB mode and emulation mode, with different luminosity. One can't do that directly, because trying to emulate AdobeRGB just stores the profile in the AdobeRGB mode automatically. So instead, I open the AdobeRGB ICC profile in the setup interface of the display, tweak the settings a bit so it's no longer recognized as AdobeRGB, then set the points back so it's the same as AdobeRGB. Then I save the profile for emulation. After this, switching between AdobeRGB and emulation modes on my display should give me exactly the same picture - but it doesn't. The emulation mode clearly has more definition in dark areas. This leads me to a conclusion, that the AdobeRGB ICC profile contains some more information than what can be entered manually. Can anyone confirm that? What exactly is different? My display's software recognized the AdobeRGB ICC most likely by the Adobe's copyright. Is there any way to obtain and exact copy of Adobe's ICC profile but without the copyright (only for my own purposes, to use it for calibration of the emulation mode of my display)? Of course it's also possible that the display or software behaves differently with different profile, but that doesn't make much sense. Also, I tried recalibrating the display (in AdobeRGB mode) with X-Rite software and there was no change, so apparently the display's interpretation of AdobeRGB is correct. Comments?
