I think...
If you change the "so called colour space" or your working
space, you will not change the pixel values. If you do "profile to profile" you
will. If you use the color sampler tool to select points in the image, you can
confirm this by doing a working space change and then a profile to profile
change.
The original question was what to do with an untaged file from
a scanner the outputs sRGB (as I recall). Simply convert it to your working
space before editing.
