Yes, VueScan transfers the raw samples as linear samples
(i.e. not gamma corrected) using the same color primaries as
sRGB. If you do a scan of a Q60 calibration slide using this scanner,
you'll see that only the saturated yellows are slightly out of gamut
and some of the saturated cyans are slightly out of gamut. Since
these colors occur rarely (if ever) in real photographs, this isn't
really a problem.
