lightroom has been fully colour managed since day one.

there is a difference between managing color and managing appearance,
look up CIECAM02 on wikipedia

viewing environment like a light room is one variable in appearance

What exactly do you believe is a *light room*?


a viewing environment a lab makes an agreement with its customer's as to
how their final product will look in their viewing environment

yes, this can can be a monitor setup, that involves viewing angle and
other "appearance" facts other than just "color"

could be a lightbox too ...

a monitor environment is a soft proof
a prepress proof in a light box is a hard proof
etc.





Understand that any viewing environment is going to be influenced by amient
light, regardless of the specific light source be it day light, or any type
of artificial lighting.


not to be over-complicated, but why would CIE come up with CIECAM97 and
CIECAM02 if they didn't think environmental factors influencing
appearance in a worthwhile workflow

Windows Vista did CIECAM(date?)

did you look up CIECAM02 in wikipedia?



What is your specific, or special purpose/interest for needing this specific
icc profile for a *light room* (not LR the app)?

managing appearance



It doesn’t sound as though you have any interest in color management for
photography post processing.


color is just a part of color appearance

there are other factors outside the realm of CIECAM that influence
appearance, like interimage ... one interimage factor involves
composition of the photo, another is user "look and feel" preference
other than accurate reproduction ... "look and feel" can be handled in
ICC "abstract" profiles

consumers prefer bluer blue skies than they really are, and greener
grass ... professional customers have their own preferences too




I think ICC considers CIECAM02

You think?

not an expert at it, should have displayed more confidence since I know
some of it


CIECAM02 is a color model.

it is a color "appearance" model



Perhaps looking at the entire Datacolor, and/or X-Rite Pantone sites might
provide some information regarding color management outside the realm of
photography. Some how I don’t believe that anything us photographers say is
going to satisfy you.

I am familiar with a little more than the basics of
instrumental/absolute color management ...

the name of the product "Lightroom" reminded me of light boxes and
viewing environment setups used for soft/hard proofing in prepress ...
and film/paper design

for pro-sumers absolute color management might be a good enough
workflow, I was interested to see how relative color management ...
appearance models ... have progressed in the professional markets ....
