Dolby Vision on this TV is not usable. Below is an example screen shot. This is The Hobbit 4UHD Blu Ray using Dolby Vision. The image gets destroyed in low light scenes. This happens worse in Dolby Vision Apps such as Netflix be and happens in all apps with Dolby Vision. HDR does not do this and displays correctly. It is only Dolby Vision that does this and I have reset the television and tried every combination of settings and nothing fixes it. This is a tv firmware issue and needs addressed because it's been going on for a while.
