Why is the color of the obj I imported with mtl texture different from the color rendered by blender?

Describe the issue

When I used it, I passed in a correct set of obj files and corresponding mtl. The color it rendered was cold. I tried many models with the same result. I checked the code for importing obj and copied it. In the blender python script, blender rendering is normal

Minimal code example

objs = bproc.loader.load_obj(obj_path)
# define a light and set its location and energy level
light = bproc.types.Light()
light.set_type("AREA")
light.set_location([5, -5, 5])
light.set_energy(2000)
# define the camera resolution
W ,H = 256, 256
bproc.camera.set_resolution(W, H)

Files required to run the code

Expected behavior
