>>5001655Honestly the tilt is small enough that it should be fine, although if you do care enough I'd recommend to rescan in grayscale, and reduce the exposure since these are overexposed.
Also put some black paper behind the page as you scan it to avoid bleedthrough that's showing on some pages (could also be from the overexposure though).
Instead of fixing the exposure, if your scanner supports it you can also scan in 10bit and then level it to 8bit.
