No, you'll get the video calibration in all apps; its just the profile 
definition you won't get in anthing but Photoshop and other color 
managed apps...

It will neutralize your grays, and make your midtones midtone, but it 
can't fix the definitions of the color primaries, as that is the job of 
the profile. That was one of the things that Windows hoped to fix with 
Vista, but didn't manage to include: some way to assume something other 
than sRGB at the OS level so that wide gamut monitors don't 
oversaturate colors. We, similarly, are working on using the monitor 
profile, not just the calibration data, in our Before and After window, 
so that (again) wide gamut monitors will not be oversaturated, even in 
After mode, as they are now.

Yes, the oversaturation you are seeing in non-profiled locations is 
most likely caused by the wider gamut. You can prove this for yourself. 
Open the PDI test image in Photoshop, and do a "Convert to Profile" 
choosing your monitor profile as the output space. Then save a copy 
("PDI WideGamutRGB") and view THAT in a noncolor managed enviromment. 
This would be the equivalent of viewing in an app that converts for 
you. Should eliminate the problem, if what I see in your sample images 
is what I think I'm seeing. Usually its the yellows, greens, and Cyans 
that are most effected, but you seem to have a extra saturated red as 
well...
