PS5, Lite mode, blurry and smudged on 4k TV?

Hi everyone! Thought about getting back into this game to check out the DLC, but it just doesn't look good... Running on PS5, Lite mode, and using a 4K TV. It just looks so blurry and smudged. Anything I can do? Running on performance mode or high resolution mode drops the frame rate so much it's not playable. Thanks!
