I think...
Profile to profile changes the file(pixel values) but changing the "so
called colour space"  or you working space should not. When it is saved it
will have the new profile though.

If you ues the color sampler to select samples in the image, and apply
"profile to profile" you will see changed pixel values. If you change your
working space you will  not see changes.
