Is this vynil or real wood?

I'm seeing more photos with this type of look, the same wood flooring and background.

Based on the reflections on the back wall, I would say it is wood flooring, but I could be wrong.

The lack of reflection makes me think it's wood too. I'm seeing shiny spots and flat spots in the grain which make me pretty positive it's wood. You can also see some curvature of the planks, and a slight unevenness to the edges.

That said, the manufactured/engineered woods and laminates are incredibly convincing these days, but they've all got a uniform finish to them.
