It did?
If you're going to use paper-specs in comparison - than you should do the same on the PS5.
But yes - PS4 games typically had up to 77% extra pixels (or less), with other settings improvements, so if you're measuring with pixels, 100% almost never happened.
which makes these numbers even crazier, like, we are talking a more than 100% uplift in res at times + max settings compared do medium/high + more stable framerate.
and all that on a GPU with a 45% increase in performance.
so these numbers are either made up, or severely misleadingly stated, either on purpose or accidentally.
we would need to know the average resolution and average framerate on both systems in the same scenes. but laying out the numbers like this, where the base model apparently needed an extremely aggressive DRS window all the way down to 1080p to keep permance up, paints a picture that doesn't really make sense.
