I'd say there is a range, as there always is. I've seen fantastic and clear visuals of FDTD simulations of laser interactions in my field in 3d, then, I've seen jet used to pcolor data that ranges from positive to negative. I would say though that a good enough fraction (not sure if it's greater than 50% but I wouldn't be surprised if it was) do care about making good figures.
