You are correct, I've used a wrong term: should have said rim vs wheel - my apologies - it was not intentional.
Based on the rim weight info I could find, ZL1 5 spoke rims are 11lb lighter then 10 spoke black rims. So it would make the front 5 spoke rim weigh less than 25lb (black ones weight 27). Z/28 rims appear to be in the same range based on posted shipping weight. ZL1 Rears would be a bit heavier as they are wider than fronts.
