I'm a programmer. I have an image editing program. I open an image

save the image, but there's no existing profile information. I have
to assign a profile to it. The only source I have is - you guessed it
- the display.
My user has made the image look the way he wants using his display.
The most logical thing to do is to embed the display profile.
You are absolutely rigth Matt, that is the right thing to do for the
app you describe. In this simple editing app you wouldn't have to
worry about matching data at all, and when you save the image you'd
embed the display's profile into the saved image file.
If you wanted to make the app more elaborate and Photoshop-like, you
could have a notion of a content creation color space (working space)
separate from the display color space. In that case though you'd have
to add the additional step of matching from the working space to the
display each time the editing window is updated, basically assigning
the working space's profile to the data and matching to the display's
profile. In this app, you'd save files with the working space profile
embedded.
