No; it's totally linear.
Form your own table:
32764/19128 = 1.713
65525/32762 = 2.000
So it isn't exactly linear. From these two points (essentially all
you posted) it looks like there is a gamma-esque hump in the transfer
function. You should fetch gnuplot or a similar plotting tool and
plot the entire "real" vs "photoslop" correspondance you obtained.
