Try to set caustic blur to 0.2 or more and(or) set kernel to PMC.

why caustic blur let pass the sunlight?

set to zero it blocks the light set to any number the light start to pass through.

It works like a filter that blocks caustics or let pass them? Works only on specular mats?

It is not clear for me yet.

The way I see it, it's like a "shortcut" fo caustics calculations.
Greater blur value = less accurate caustics, but faster converge time. Leaving it to zero doesn't block light, it just takes waaaay longer to calculate.
