I am trying to copy an animated video. It can be found here.

I have not found a way to perfectly replicate the same background color. As it looks to me, the original authors may have used a curved mesh.

That is what I tried to do, too:

However, it still does not look right. The device lacks highlights, I think. I am not sure what I have to change to make it look right. I am also not even sure if the curved mesh is the right way to go.

Thank you for any input. Because it might be difficult to answer without any insights, I have uploaded the blend file here. It was too big for blend exchange.
