Sure, some just do pixel art for budget reasons. In those cases it's still a limitation rather than a deliberate choice. But for example Hyper Light Drifter is modern and I consider it one of the best looking games I ever played.
It's not a technical limitation though, which is the thrust of the convo regarding Doom's lack of ray tracing or other fancy effects. Doom was low budget as well but still hired artists. As far as I'm concerned, making a game without an artist is like designing a static HTML webpage in 2022. Yes it will work, but is below the expected standards.
