No Man's Sky Astroneer, Enshrouded are not voxel games AFAICT. Of those, I've only played No Man's Sky, which I agree at some level is similar to Minecraft in gameplay
Here's a GDC talk about No Man's Sky world generation:

Voxels doesn't necessarily mean something looks blocky like Minecraft.
I used to read this guy over at procworld.blogspot.com (as I type this I'm not sure if it even works anymore) who developed a very nice Voxel engine he ended up eventually licensing to game studios like SOE named Voxel Farm which was intended to be in EverQuest Next.
It had tons of features way beyond a simple Minecraft clone. I was always blown away at what was possible and the tech behind it.
They use voxels under the hood but still render smooth graphics with techniques like marching cubes.
I think you are underestimating voxels or don't understand how they are applied in modern game development.
If those aren't voxel games, neither is Minecraft.
That's like saying games don't use polygons or triangles to render because when you zoom in everything looks smooth / no triangles.
