Technically yes, all wood ages with time. But oak doesn't age drastically like other woods.

That should not be the same floor. Looks like the sample board is clear coated with a matte or oil finish. The small has been treated with white wash before coated. It would be helpful if you can lay out a few more floor boards. The natural white oak floor should like this after installed.

Cicerone Lager

Both have been clear coated.. One with oil base the other with water base.

Strip in the center is natural with no coating.

"The company said their natural oak floor is now this color and has more wire brushing than the sample we saw at a store."

In other words, they sold you a different floor.

Our floor installer Recommended that we purchase a full box to lay it out We did and we were totally sold, we went with another color and delivery day they stated that they were much darker and they were we declined to take the truck load of flooring went back to the original of that we purchased figured it would work had it delivered and had a couple different lot numbers and what is a more reddish tone that also went back or third choice was a charm good luck with your floor, Hopefully if it was delivered they woutdoor take it back
