three.js – How to get visualize the object same like Sketchfab?

How can I the 3D model look same like as it is in sketchfab’s site ?

I bought a 3D model from Sketchfab. The model looks great on their site with proper lighting. When I load the glb in a third party glTFViewer, it was still ok quality (but not as good as show on the Sketchfab site). But when I load it in my three.js app it looks terrible.

First image is what I want (from sketchfab), second is what I see in an online glTFViewer. Third is what I get in my three.js app.

How can I make it look same like the sketchfab’s ?
