Then, what is it that capture device captures? I mean, what is the raw
data's space? If it is larger that the subsequent RGB Working
Space, then -- is there a kind of conversion/clipping (upon raw into WS)?
If yes, then I'm wondering if conversion from raw into LAB could still have
more original information preserved than what we get landing in RGB WS?

For archiving purposes? I mean, sometime in the future a better output
device will be able to squeeze out of LAB more than out of a particular RGB
WS? Or there are RGB WSs which encompass the whole possible eye-range
anyway?
