There was a Lightroom podcast specifically about this topic. Featured
were Bruce Fraser and others discussing RGB numbers and Colour Spaces.
The 'cast is still available at the iTunes store - it is Podcast 8.
Best,
Nick.

Processing color space is linear encoded gamma using ProPhoto
primaries.
Histogram and numbers are ProPhoto primaries and an sRGB TRC (kind
of 2.2
gamma encoding). Then, as mentioned, you have an option for three
encoding
color spaces of which the numbers have no direct correlation. In
ACR, the
numbers are directly based on the encoding color space set but
that's not
how it works in LR.
There's a bit more about color management in LR here:
