Thank you for your suggestions Johannes and Walt,
The way I work, I want to correct the original RAW image first (with setting black white and grey points) that way I can (as desired) remove or manipulate a sensor colour cast of a camera and
determine the detail in the darker and brighter zones of my image, With these corrections done I can process my image to wherever I want to take it.
I am not sure I can pull it off with the info panel Walt.
It is somewhat like you see here. http:// https://www.youtube.com/watch?v=rvv8NeeYEeI&feature=youtu.be&hd=1
I do a lot more though, I make three separate curves adjustment layers for Black White and Grey and correct in each adjustment layer the sampled values for the Red Green and Blue channels
for my blackpoint I set the rgb values to 7, for grey to 128 and to 247 for white.
With these 3 layers I sometimes change opacities and their stacking order to taste.
Thanks for the suggestion Walt to float a finalized image next to a copy rendered with my icc profile.
Yes I can softproof with an adjustment layer (thanks W) but regardless of where the icc profile comes from (I agree with J that a printer generated one is best),
I really want to softproof while the screen shows me what the result will be on a particular paper; to avoid printing something I don't want I use a proof setting
that toggles how the colours pan out when they are printed (by the relevant printer) on the particular paper the profile is made for.

I hope I have shed some light on my ideas and wants. Thanks both for your insights on this.
