I am not so sure that images in GIMP are "edited in sRGB colorspace".
You are right: I forgot that Gimp let the user choose working colorspace...
But as you explain later, Gimp is not able to read embedded profiles. So
you have to choose the working colorspace, which much match the colorspace
of the image. Usually, sRGB, as most DSRL cameras output files in this
colorspace.
Some do some don't and some also let you select from several that are used by
the built in camera image processing. sRGB and AdobeRGB are common. If you
have this option and you are using in camera image processing then use
AdobeRGB has it has about a 45% larger gamut than sRGB.
This is not necessarily sound advice. A wider gamut is nice (if you
can see it), but there are other factors to consider. Image
processing done in the camera likely ends up with 8-bit JPEG as the
result. 8 bits is not very much and by selecting the wider gamut you
may lose useful color precision. If the target usage is sRGB (e.g.
for a web page) more information may be preserved by using sRGB in the
camera.
