70D nylon holds a lot more WP coating than 30D nylon.
Look at HH test results between the 2.
It depends on the coating thickness. If you put the same PU coating that is on most 70 denier nylons on a 30 d in the same thickness, the waterproofness will be the same. You are comparing a silicone coating to a PU coating and are negating different thicknesses of coating.

EDIT: examples

70 d at 2.5 after coating. 1.9 before

30d at 1.3 after coating. 1.1 before.
