There is no spacetime curvature in a uniform gravitational field. It's a myth that all gravity is a curvature in spacetime. Curved spacetime is the same thing as tidal forces and a uniform gravitational field has no tidal forces.

What might be an example of a uniform gravitational field?

The surface of a sphere  with all the mass at the centre?

Consider a sphere of uniform mass density. Now cut out a sphere inside whose center is offset from the sphere's center. The gravitational field inside will be uiniforrm.
