Rendered in KS.. Post processed in PS..
The use of Philips® Logo is just to add more realism to the render.

Nice renderings. If you're going for a more shiny/metallic metal look, try a studio environment with more contrast/sharp edges. Looks like you're using something similar to the startup environment which doesn't handle metals too well.
Very nice shot. Can you please explain how did you create the shadow on the ground in the first and second image?
Is it a Keyshot trick or PhotoShop?
