Sorry to be a pain in the *** ..but this is important and I can t agree with your explanation as I understand it .
Just to clarify .....I completely understand that the raw conversion software is applying its own presets and calibration in the RC software.
Lets just focus on what happens in the camera ....the cameras processor takes the raw sensor data and creates the initial raw file (along with an embedded profile ) . How the camera manufacturer decides to map that data ..does have an impact on the raw file . Lets just look at the Sony sensor used in both the Sony A900 and D3X (or use any over example you want ) . We know for sure that the D800 and D800E have the same sensor. Nikon decides exactly how to map the tones and colors into the raw file and they have a different approach than Sony . It is how they do this that is the key to some of their high ISO performance . The “raw file “ represents processed sensor data and each manufacture has its own signature .
I understand the problem Guy is speaking to is really about the fact that neither C1 or Lr appear to have a D800E profile and this is the source of his “need to change “ . However I would tell you that the same exact problem occurred with the D3s and D4 ..where they have had time to get the profile correct .
This only matters because I have found (starting with the s2) that some raw files just never quite get there until the raw conversion software is refined enough to handle the new raw file ....even though you would think that you can adjust all the parameters in post processing . It also explains why no one seems to be able to match cameras from different manufacturers (if its not mapped into the raw file you aren t getting it in post ).
I realize this is beyond the discussion that Guy initiated .
