Jeremy, the only reference I can find to this is in another thread on this forum that was talking about white balance.
It appears that the term 'camera raw settings' refers to the white balance at the time of RAW conversion.
Apparently it marks an attempt at changing white balance with the white balance eye-dropper that Lightroom rejects because of potential clipping of the red or blue channels in the attempt.
So, the term 'camera raw settings' confirms that the original white balance has been retained.
Funny isn't it, I have some pretty robust reference works for Lightroom and I could not find a reference to this term.
