Let me try to define the terms nevertheless. Perhaps that helps to clear up some of the confusion around this topic. We speak about an embedded color profile in the context of an image file. The file contains a color profile and this profile defines how it should be interpreted. Not all file formats actually support this. We speak about assigning a color profile in the sense of assigning the "icc-profile" parasite to an image object in GIMP. This is what a file load plug-in will typically do. If it finds an embedded color profile in the image file, it will create an "icc-profile" parasite from that profile and attach it to the image. This attached profile will be used by the display code to correctly display the image and when that image is exported, the file save plug-in may embed the attached profile in the file that it creates. Some file formats, such as PNG for example, allow to tag the file to be in a particular well-known color space. The color profile is not embedded then, it is assumed to be well-defined. Instead of distributing the profile with the image file, there is just a flag saying "this data should be interpreted as sRGB".
