Aside from some OS level specific issues (such as Apple's ColorSync screwing up users or some driver problems of double color management on Windows) no, not much has changed. Sure, X-Rite bought Greytag and consolidated software/hardware offerings...but the purpose of those tools remain the same. The only main thing that has changed is that digital photographers have moved deeper into raw image processing on the front end of input into Photoshop with ACR/LR and the use of DNG Profiles for camera profiling instead of trying to make ICC profiles for cameras.
But, having talked to Andrew and other color geeks, there's not much need for (nor desire to) substantially revised books on color management.
Well, a few things have changed. We now have CIECAM02 which is used by the WCS (windows color magement system, see
Steve Upton) and ICC ver 4. These may not be ready for prime time, but could help with the poor state of perceptual rendering for screen and print.
Joseph Wisniewski claims that applications use perceptual rendering for screen output and this is confirmed by Ellis Vener who frequently posts on LuLa and who appears to know what he is talking about. Andrew Rodney points out that available matrix profiles lack tables for perceptual rendering.
I've profiled my monitor as shown below in the first screen capture. The profile is tagged that Microsoft is the preferred ICM and the preferred rendering intent is perceptual. However, I don't the profile contains perceptual look up tables.
My color settings in Windows 8 are shown.
I don't have the slightest idea of what is going on and would buy a book that contains up to date information.
