MGS5 doesn't seem like the best of examples, given it's a cross-gen title. It's certainly a very well done one, but its 7th gen foundations are pretty obvious. Also, as Miguel mentioned, it cost enough to be the final nail in Kojima's multi-decade relationship with Konami :p
I can understand where you're coming from spemanig, i feel a similar way about IQ, but at the end of the day the average gamer simply does't seem to care much in most situations. That makes frame-rate an easy target for a developer that wants to make a game that pushes 8th gen tech, and doesn't want it to look shitty as a result. I'm personally totally okay with that.
On a side note, i'm a bit confused as to why you thought of Bloodborne as 'the first truly next gen game'. It was a pretty game, but that was mostly on the back of its art-direction. On a technical level it was nothing remarkable.
