32-bit color picker displays wrong values of low values of RGB. I have created, as an 8-bit image with boxes filled with RGB values of R=8, G=7, B=6 -one box, R=5, G=4, B=3 -second box,  R=2, G=1, and B=0 -third box. I've saved the file and reopened it converting it to 32 bits. When I read the values for RGB, I get 191, 167, 143, ... . The color display reflects these values. Only with B set to zero in the third box is the value for B correct. The 32-bit fp values seem to be correct. When looking at many values of the 32-bit fp numbers, I see a very non-linear return. Any ideas? Looks like an Adobe problem.

Thanks. I've asked engineering to take a look.
