For the love of god. I think I need to make some clarification here:
HDR IS BROKEN AND WILL NEVER BE FIXED - Game was made for SDR. You can't fix this by messing with TV settings. Turn this off
Motion blur is different to the extreme bluriness of the game that PS4 Pro users in 4K are encountering. This happens only when you move the camera as its name says "Motion blur". This is on both Xbox and PS4 versions of the game.
Only way to fix blurry view on Ps4 Pro for now is to uncheck SS in video options and force 1080p. There is no other GODDAMN fix so stop posting some silly TV settings pretending them to be a fix for all your problems. Yes I am also playing at 1080p now because on 4K blur is so intensive that it gives me headaches and no, I don't know when they will fix it.
