More than works fine - I prefer this spot so that I always look in the same place to see what's behind me whether I'm going forward or backward. Taking your eyes far away from any windows to focus on a tiny rearview camera view while reversing makes it hard to see other motion with peripheral vision.

Lots of after market mirrors support this, but admittedly I've only put them in cars that didn't have a camera to begin with.

My car has both options. I think the idea is you'd use the rearview mirror display primarily at night as an always-on display in place of the anti-glare polarization toggle that some rearview mirrors have, while using the center console for backing-up.

I prefer the center console. The rearview mirror is shaped and sized to display the small sliver that you can see out of the rear window which are tiny these days due to increased pillar width, and rounded back to improved crash safety and aerodynamics. The size and aspect ratio of the center console makes it much easier to see details, and doesn't have to compete with bright back-lighting from the sun. Increasing the size of the rearview mirror would be an option - don't know how big you can get before it starts impeding forward view (again, because the front roof slopes down more for aerodynamics than they did in the past).
