Gave my life proof fre another run over the weekend, i like the thickness and protection but YES i have the oil slicks, those that say you can only see when screen is off are WRONG, they are very visible with a white background i.e. mail or safari especially outdoors.
Probably a case to use if you are going near water and want to video or photos or a tradie etc, which would make the NUUD useless as no screen cover.
Just ordered a Genuine Black Silicone see how it goes have never had one, the black Apple leather i have has marked/scratched easily, even a light finger nail will scratch it, i take care even of my cases and its just ugly on the back, not just marks but the leather quality just looks and feels slimy cheap. Wouldn't get another one and i do like leather.
Glad i got it free.
