I don't own a Note 4, bit the last 4 phones I have had plus my N10 have all had Supcase brand cases. Never had any issues with marks on the phones or tablet caused by a Supcase. In fact the N10 is in the original Supcase I purchased for it. I use the tablet daily & take it with me often when out & about, including work & on my motorcycle. The case is looking slightly worn after over 2 years, but the tablet looks practically new. I work outside for my job & my phone is exposed to stone dust, dirt, moisture etc. So I consider myself a Hard use case for cases. I have had my Moto X in a Supcase Unicorn Beetle hybrid case since June. Have had the phone for a year. When I take it out, the phone looks new. So, in my experience, if a case is damaging your phone, its time to get a different case.
