Hi, I think the VirtualBox shouldn't make a difference. Screen calibration makes a huge difference, though, and I don't know if VirtualBox can handle that.
To move rulers more precisely try right-clicking on them, on the top of the curve that shows you can change them quickly, on the bottom finely. And you can type numbers into that field, if you know you want a +.0.025 change. For a more automatic approach, try the Equalizer and Tonemapping/Global Tonemapping modules. But in general, darktable is not as good as Lightroom in "getting it somehow right automatically", while it allows to fiddle more in detail.
