Halo 4 looking better than Halo 5? Can't say I felt that in playing. I felt that Halo 5 didn't feature a substantial jump in visual fidelity, though. And in Halo 4, I remember the opening in-engine shot of Forward Unto Dawn looking like unlit garbage, especially right after the Blur Studios rendered cinematic. There wasn't any such jarring adjustments in Halo 5, that I noticed.
