Is there any way to achieve that effect with MSP as well?
I hope MS is not going to compete with image editors and become Jack of all trades.
You need something like Photoshop or GIMP. Find Gamma slider which changes midtones while keeping the blacks and the whites the same. Increasing Gamma makes dark areas darker and light areas lighter.
I'm afraid you need to adjust every bad PDF/image/scan individually.
