If you take a good skylight or UV filter, such as your lens protector filter, and look at the reflected image of the sun disk off that, you will see how bloody bright it is, even for good filters where the residual reflectance is less than 1% over the visible range. I have one of those super Hoya filters, which is only 0.3% reflectance, and it is still too bright to look at.
Then imagine cutting it by from 3 to ten times, and you can appreciate, it isn't going to be invisible. Like you say; the camera sees all.
PS I don't think fuzzing the leader does much, besides weakening the hell out of it. The slight scattering caused by non-destructive surface roughness, will virtually disappear under water anyway, because the index mismatch is much less, and the change in optical path length from point to point is greatly reduced, and it is that p-p optical path variation that makes it not look sharp.
