Personally I look at the more powerful systems and I can easily appreciate the stunning visuals of the Order, Battlefield 1, the Division etc but at this point, none of it wows me anymore. Sure they look stunning, but the race to more realistic graphics has just gotten stale IMO, and 4K and HDR nonsense certainly won't change that belief.
On the other hand, I look at the less powerful Wii U and the visuals of say, Yoshi's Woolly World, Mario Kart 8, Wind Waker HD, Paper Mario Colour Splash, Captain Toad etc... just beautiful games. THOSE wow me and it's hugely exciting to see what they think of next. Unlike say, the next Battlefront, or the next Assassin's Creed that'll just look like a slightly prettier version of the last one, or with slightly denser crowd scenes.
