Like with Klingon ridges, the Enterprise-D's bridge has ALWAYS looked like this.
You missed Star Trek - Enterprise right?
They did not just change the bridge, but the whole ship went through a refit of some sort.
Take Engineering for example, when Riker walks of after he discussed the Romulan Tricorder with Worf, he turns into a hallway, which was never seen in the series.
The corridors on the ship look much darker. Even Picard's readyroom got a redress.
