Can anyone verify this color problem

Question

Importing a photoshop solid color green,(72, 182, 70),  file (tif adobe98) into Aperture 3.2.3 on a lion machine.  When this file gets imported to aperture the color changes dramatically.  When I convert that same file to sRGB in photoshop and then import it into aperture it looks as if most or all of the color was NOT lost or hosed as the Adobe98 file was.  Can anyone explain what is going on?  Thanks Ireally want color management to work.  david

Thank you for your help. I am glad that I am not alone with this problem. I feel it is a really huge error, but most people don't care, because they don't own a wide gamut display. If you don't see the problem you don't miss a solution.... For sure the Apple Aperture folks use Apple Displays, they can't see the problem too, if it exists outside my own Aperture installation. To verify this I did the following:
1) Fresh installation of Aperture: Trashed Aperture.app, trashed Aperture Application settings, reinstalled Aperture 3 from DVD and did the 3.3.1 update. Made a new library. It did not help!!!
2) Used my Macbook Pro to verify. The same problem!!!
How can I verify this on a Laptop display with really small gamut? This is a way to test it for you without owning a WideGamut Monitor:
Download the already known display gamut test image:

Import it in Aperture
Open it in Photoshop independent from Aperture
Be sure that View > Onscreen Proofing in Aperture and the similar in Photoshop is OFF
Place the both application windows beside each other, as you can see the both images at once. I estimate at this time you can't see the stripes not in Aperture and not in Photoshop.
Now change the system wide display profile to "Wide Gamut RGB". If the problem resists in your system too, you will see the background stripes in Photoshop but not in Aperture.
It looks like in my screenshot here:
Left Aperture: No stripes, right Photoshop: Stripes in the second and third image.
To switch to WideGamutRGB is nearly the same as using to the CG301 Eizo profile, the difference in seen colors is not huge at my MacPro. On my MacBook Pro it is a way off, but it simulates that the Laptop display has WideGamut. The display gets the 0-255 steps in colors from the graphics card but these steps are in a much wider color space. So the LCD of the laptop gets compressed colors with the steps in the background compressed to the 0-255. The result are terrible colors but you can see the driffernece of the steps too.
I hope my explanation was understandable. If your test shows the same as mine I think we proofed a really big bug in Aperture. For me it is catastrophic, because I am a big fan of Aperture. Its workflow, its smoothness, the look and feel, the print module etc. etc. everything is nearly perfect. But not with this severe colour mangagement problem that forces some kind of sRGB for all image editing.
A note: This testimage is specially made to value the quality of monitors regarding color gamut. If you see the stripes in image 2 it is okay for AdobeRGB, if see them only in image 3 it is good for sRGB, if you see them not at all the gamut of the display is less than sRGB for the color red. Thiss tells the legend on the right side in German. To see the stripes with all displays you can switch of the blue and green channels in Photoshop.....
