No reason to believe that they would, I've been on multiple planes where it was possible to bring up different camera feeds of the plane on the screen in front of me. The coolest of these was filming the plane from the top of the tail wing so it almost looked like a video game feed.

This sounds really cool, what carrier and aircraft type were you on?

Singapore's A380's LAX-NRT have this.

JAL had it, too, on ORD-NRT. A member of the crew would switch to different cameras, presumably based on what there was to see (front landing gear view during takeoff, just clouds straight down during most of the flight, etc...). I haven't flown JAL in close to a decade, so I can't say if its planes still have this.

I think this is an A380 feature, needed to accurately steer the thing on the ground. Other airframes of similar age may also have it, though I've been on several 787s and haven't seen anything quite as neat as what the A380s have.
