I think such a featute should be inside of Aperture beause thats the App were I manage all my photos. Take a look to Lightroom and it has the ability for that or Photoshop since version CS by scripting.
I disagree.
Apple had the idea of simplifying applications by supporting imaging services in the operating system and not in the application.
This applies as well to the idea of intelligent drawing transform (ColorSync and TrueType) s as to the idea of an intelligent display model and an intelligent print model.
It is better for the everyday enduser that the operating system should supply a single interface than that software publishers should supply as many interfaces (and as many implementations) as there are software products.
Adobe tried unsuccessfully in the transition from its past separate software tracks to its present single Color Studio software track to achieve some of the aims Apple sought to achieve in the past. Better that Apple progress its aims than that Apple adopt Adobe's chaotified approach.
The gamma rendering atop of ICC is in case the same I get if I print with the Epson driver, were in the settings menu is the same function - only with a different name labeled. And this kind of gamma setting you can find in RIP softwares too.
As posted, in characterising a colour display the gamma calibration is part of the characterisation. The calibration and the characterisation are inseparable. For what it's worth, I published the VCGT Video Card Gamma Tag when it first appeared and pressed as well LOGO as Heidelberg to support it.
Similarly, transfer curves are permitted in PostScript (they can be programmed in Photoshop) but they are prohibited in PDF/X because they change the state of the RIP independently of the state of the system documented in the ICC PRTR Printer profile for the printing condition.
It is irrelevant what RIPs do, if what RIPs do is not technically correct.
