These textures are very easily the best textures I’ve ever come across.
— Peter Roe
I think the main "problem" is the lack of surronding objects in yourimage, therefore you cannot compare both images. In a scene like yours there is nothing that could be reflected. If you complete the scene with ground and walls etc. you will see a big difference. The objects in your scene will "interact" with eachother.
Hope this will help you a bit.
