That just seems crazy to me. The whole idea of a device profile is supposed
to describe the color the device creates. The whole idea of a colorspace
like sRGB is it's got a certain "DNA" that makes it different from all other
colorspaces. What you're saying is fascinating but also very unsettling. Is
this all within the ICC spec or did these camera manufacturer just make a
big Frankenstein monster out of all this?

Ah! So it's the conversion INTO sRGB that accounts for the differences? That
makes a bit more sense.
In the end, I have to wonder if having more than one input method for
conversion into the same space (sRGB) is a good idea. And why (thankfully)
only one rendition of Adobe RGB (in nearly all the cameras that provide
multiple sRGB)?
