You're right about this, of course. You do have to worry about display gamma and image transfer functions, etc. But if you're comfortable with that it doesn't have to be too hard. It depends on the data. Sometimes inverting the data/colormap works well. Sometimes a log transform helps. Or squaring. Or square root...
