Unfortunately, I don't have an altogether satisfactory answer to your specific question, but I can tell you that Color Management is nowhere as up to date in Illustrator—not sure about InDesign—as in Photoshop.
Despite the unfortunate marketing move of bunching the applications in a so called "Suite", the point applications are developed totally independently by different teams that are located not just in different cities but in different states of the USA and even in different countries.
Collectively, I'm certain that users of these forums could draw up lists of color management deficiencies in Illustrator compared to Photoshop, but that would be just an exercise in futility.
When it comes to critical color, I only trust Photoshop.
You could, of course, also post in the Bridge forum for the platform of your choice, Macintosh or Windows.

One thing that comes to mind is that PDFs saved in Photoshop are essentially one-page image documents, while those made in other programs may contain all kind of different objects, not just image objects, but also text objects, for instance. They can also be multi-page documents.
When you open any PDF in Photoshop, regardless of where it was created, it is immediately and inexorably rasterized.

In short, your question is really an application-specific issue, not a Color Management one.
Another relevant thought:
Bridge started out as Photoshop's Image Browser, no more and no less.
Thanks so much for your help, I didn't know any of those things. Very interesting.
In regards to Photoshop rasterizing PDFs, what exactly are the ramifications of that? A PDF-X saved from Photoshop is still fine to send to the print press, right?
So far, all the print work I do I design in the colour space specified by my printer, then save as a PDF-X1a (which is also what they specify), by doing 'Save As' in Illlustrator. I also name the file with the colour space, and my printer has not had any problems with this.
The reason I'm asking about colour management, is that I may start expanding into the area of designing adverts for newspapers and magazines, and this involves different colour spaces. And newspapers etc. around here won't be as fussy about colour management as my print-press, which is a very good print company. So it would be better if I knew they were getting PDFs from me with embedded colour profiles.
I think the situation is that when I save things with embedded profiles, that it does in fact work, despite what Bridge, Illustrator and InDesign say. I have .ai files that show up in Bridge as untagged, but when opened in Illustrator, do indeed have an embedded colour profile.
It's very confusing to know what's going on.
A rather non-technical workaround, which alot of people seem to use, is just designing the file in the correct colour space, saving the file in that colour space, naming the file with that colour space, and then when it gets to the printer/magazine/newspaper etc. hoping that (A) there is colour profile data in the file that people can see at the destination or (B) the people at the destination know from the file name that you designed it in the correct space, and so they just Assign Profile at their end, and all is well.
I mean, what's the alternative, I can't suddenly stop using Illustrator and InDesign, and doing ALL my work in Photoshop, just because of what Bridge says!
As I suggested in post #1, I think you should post in the Bridge forum for the platform of your choice, Macintosh or Windows.
You are describing an issue you see in Bridge, and the Bridge engineers should be able to tell you if this is something they can fix in future versions or if it's up to the Illustrator and/or InDesign teams to fix it.
