There are hundreds of useless objects and items all modelled and interactable with the world of Starfield each one receiving light from GI and casting their own shadows and reflecting as well. All of this with a properly applied physics model to them and with permanence in the world. Each item is an actual object in the world, and it’s very different than ejecting some bullet casings that stick around for 30 seconds and the disappear.
If you’re only looking at what materials people are posting about Starfield you sort of only see what’s bad and not what’s good. That’s sort of the difference between playing the game and seeing what pictures people are posting online.
Starfield is one of those games you gotta play otherwise you rely on players with a good eye to know when they are looking at something great to take a photo of it and that’s an artistic skill of the player.
This thread pretty much sums up the different things you can see:
It's the first shot of the game that I see where a planet cast a shadow on it's rings. Modded on PC?

As per what Starfield does correctly:
I think this scene actually captures its lighting solution as a whole.

Look at the shadows all resulting from different light sources. look at the mixture of lighting. Look at the reflections in the glass. All of this is done dynamically and none of it baked. That’s just not something last gen games could do.
