I have noticed that in the Header portion

itself not sure, my question is can this be changed and are there
noticeable results between these settings. Any explanation on
this subject
would be great.
strictly speaking the bit flags are part of ColorSync, not the
ICC spec. But they do use bits that are reserved for 'vendor'
use.
My understanding of it is if the bit is set, ColorSync will
dedicate more memory to make a larger LUT in RAM when performing the
color conversion and this might result in higher quality.
I doubt any other CMM sees the bit or changes its behavior based
on it so if you live life using the Adobe CMM or others it probably
doesn't affect you.
ColorThink Pro will show the state of the bit and let you change
it, I'm not sure if there are other tools that do.

Steve
