VfSU Linear Workflow

I'm trying to improve my renders using linear workflow.
I assumed the GAMMA inside Sketchup is 2.2, also I'm assuming that my LCDmonitor is 2.2
if I use LINEAR MULTIPLY (under COLOR MAPPING rollout)
with GAMMA 1.0 and INPUT GAMMA 2.2
unchecked 'linear workflow' ------ would these settings give me correct rendered output?

the Default setting of color mapping in VfSU:
LINEAR MULTIPLY
GAMMA 2.2
INPUT GAMMA 2.2
CHECKED 'LINEAR WORKFLOW' ---- this looks like double gamma corrected on bitmaps, but displays colors correctly(colors inside sketchup = colors on VFB)
