I suppose that is because the UE does not support the color format of the .obj files that we saved. To fix it, you can try to convert the .obj files to .glb using this code snippet.

from pygltflib import GLTF2, Material, PbrMetallicRoughness
obj = GLTF2().load(obj_path)
obj.meshes[0].primitives[0].material = 0
obj.materials.append(Material(
    pbrMetallicRoughness = PbrMetallicRoughness(
    baseColorFactor = [1.0, 1.0, 1.0, 1.0],
    metallicFactor = 0.,
    roughnessFactor = 1.0,
    ),
    emissiveFactor = [0.0, 0.0, 0.0],
    doubleSided = True,
    ))
obj.save(glb_path)

Optionally, you can visualize the textured obj in Meshlab.
