Same. HDR is turned on. PS4 Pro, TV is Sony XBR X900E.
I'm also seeing significant flickering events in a number of cutscenes during the campaign. The cutscene generally starts fine, but roughy 15 - 30 seconds in the images will rapidly fade to black and back again for, idk, 15 - 20 seconds before being resolved. It definitely takes you right out of watching the content and makes you try to figure out what is wrong with the system.
Additionally, the menus / cutscenes are overly bright with halos. My loading screens always dip in brightness for a few seconds right before the mission / multiplayer starts.
