It seems to me, the color management is absolutely correct in Your case. The 
calibration only relates to grey scale. There all is ok, except the colors 
himself. The greys are correct, but the colors - not. You can see the smooth 
color scales, the flags of the parrot. But this colors are not true, they are 
display-distorted.
When You try to enable Your (correct) display profile, the CMS tries to put the 
colors to they's true values, but in many cases CMS can't. Your display have 
very little gamut comparing the test image profile. The colors become as true, 
as possible, but because of low display capabilities, the many details of image 
become clipped. See the attached image to compare gamuts: green - image gamut, 
red - display gamut.
You can try to compute image-display perceptual device link and try to view 
link-converted image without CMS enabled. So You can make sure Your profile 
works properly.
