The summary's limited scope means it regularly fails to inform the user what's going to happen. Setting aside any complaints about malformed print drivers doing the wrong thing, the UI will tell me that ColorSync is going to be used when it certainly should not be, and also tells me it will be used when it isn't. So I find the Color Matching summary to be intermittently misleading and thus useless.

For example: When printing from Photoshop CS5 with "Photoshop Manages Colors" to an Epson 3880, which has a properly behaving driver, this is an image "prematching" workflow. Yet the print job Summary panel for Color Matching says the value is ColorSync. This is clearly somewhere between misleading and wrong.

The same behavior happens with the Adobe Color Printing Utility, which was expressly made to prevent ColorSync (or application color management) from affecting ICC profiling targets. Yet again, the Color Matching value is set to ColorSync in the Summary panel.

Useless to dangerous.
