why device independent color?

if you want to purpose an image to more than one output device color,
and have the output look the same

or

if you want different input device color purposed to different output
device color(s) and want the output to look the same

then

you need to convert the device colors through device independent color
space like XYZ,CIELAB,CIELUV

I remember the introduction of the sRGB standard color space

I remember speaking on Kodak's internal ICC ( http://www.color.org )
mailing list, espousing that sRGB would be an excuse NOT to make device
profiles with regard to the device independent color space(s)

I think the use of SWOP CMYK standards had a similar result

it's been almost 20 years and it seems like most cameras are using sRGB
or ProPhotoRGB as default profiles instead of getting a REAL profile
from the vendor of the hardware or making such a profile itself

people who don't consider how far an image accurately when it is
multi-purposed in device independent color

there are few vertical imaging workflows left, perhaps there you can
translate the color by matching filtration, etc.

the only place I see for sRGB and SWOP is consumer related imaging

not to say that RGB/CMY (with/without maintenance of black channel)
isn't the best working space, I just don't see it as a profile
connection space, since there are MANY RGBs, they are device dependent,
and have device dependent color, whereas XYZ,CIELAB,CIELUV are
independent of device

let me take this time to also say that the print reference medium has
been a start with ICC to tackle appearance matching instead of color
matching, ought to be more reference mediums and implementations of such
use-cases to make better workflows
