An that account, you're absolutely right. The best phantom center (or any other channel) cannot compete with a real center.One of my theaters is a 7.1.2 system in a small room. What the surround-back channels bring to the game are two additional channels to aim objects or audio effects in the case of the upmixers. It also fills in the rear with actual speakers rather than relying on phantom imaging in a position where are ears are weak at capturing direction. Perceptually, it provides depth to the soundfield, and in the case of the upmixers, it allows them to track flyovers from front to rear better than 5.1.2 can.
If you see 5.1 + Atmos or Dolby Surround, you won't see 7.1. There are more channels being decoded than that.
