The problem is that ENB and Oblivion Remade aren't feasible for everyone, and Night Eye still ruins the game if you don't mod it. The only non-ENB mods that do that are omods and getting the ENB to work correctly destabilizes the game and crushes your cpu / gpu with extra load. Which crowds out other gameplay mods that need those resources. It's a limitation of the game being single-threaded and harshly limited by 32-bit code.
