Tanks a lot for your input.
Now when reading this from Marco, "As for the Perceptual rendering intent,
it is supposed always to map

Perceptual.

and this from Steve, " >> When converting from a "normal" working space like
sRGB / aRGB / etc using the perceptual intent, this expectation is for the
most part, correct.... at least as far as the color spaces go. The image
itself could lie anywhere of course.
In this case, BPC will probably not have a noticeable effect on the
resulting conversion."
I thought - Wow, here is practical a tool to test profile accuracy.
Doubting the quality of my profiles as I always can see a change in
perceptual when BPC is on or not, I pick up one of B. Atkinson's profiles,
which are some of the most meticulous done profiles that I know. I opened an
aRGB image run a proof preview and could see the same changes as with my
profiles when turning BPC on and off. To further puzzling, these profiles
(Atkinson's) are recommended to convert perceptual without BPC, why?
