If you played seriously then you knew enough to turn the settings lower, not higher.
The last thing you want is having your field of view obscured by colorful explosions, bloom, debris, etc. when your opponent has a crystal clear vision on you.
But that is a completely orthogonal point to the question as to whether doom runs well at 4k with all features on. Because I am asking that question does not mean I would play death match that way. But I might indeed go through the single player campaign that way.
Indeed I didn't play Doom at 4k at all, because as I said, it felt like garbage at 4k, no matter what settings, on 1070
my 1070 would do it, but it was garbage fps
