In all fairness, it takes more horsepower to improve graphics, versus say when compared to audio sound, or game-play mechanics. Of course, storytelling remains more or less consistent; but varies with audience and pop culture.
Personally, I first noticed it transitioning from 8-bit to 16-bit; yup old timer here. When scaling and 3D rotations were introduced. However, still to this day, I am extremely impressed and in complete awe standing in front of an UHD 4K set. Yes, this also includes PC graphics. And I still retain a soft spot for 3D formats.
