Gears 5 is technically above those its not comparable imo. 4k/60fps, especially with the fidelity Gears runs at, is crazy. Even DF spoke of it as one if the best looking games on PC made.
Gears 5 Was significantly more impressive as an UE showcase than Days Gone, as noted by Digital Foundry.
Ok, well, then I don't know what to tell you. I was talking about my personal taste, not what Digital Foundry said.
Perhaps it was the art direction, but it didn't look that impressive to me (I played it on PC, with HDR on, and it was a really good looking game, but nothing that blew my mind). I did like the game very much, don't get me wrong, but it didn't feel that much visually impressive (especially the red desert act, it didn't look nearly as good as the beautiful ice setting at the beginning).
But ok, perhaps you're right, memory can play tricks.
