Actually, I thought the color management in ImageGlass was borken, but it works and here's how: In the settings, image, and color management section, go to the select and choose "custom" (not sRGBB unless you've calibrated your monitor to be exactly sRGB) then browse for your custom monitor profile. In Windows 10, it's in Window/system32/spool/drivers/color. Restart ImageGlass, then it should properly convert from the image profile to your display. It should really do that automatically like other apps.
As an additional request it would be good if ImageGlass can automatically switch to correct profile when moving from monitor to monitor(in a multimonitor setup).
i just got a color calibratior and would love this, i also have multi-monitor setup and imageglass seem to have issues when you have a multi-display setup as it wont change the color profile, its just stuck to whatever is default, on my non-multi-monitor laptop it works fine
left windows, right imageglass, nef file

kinda looks like a raw issue as this is how it looks on a jpeg
