Yeah. Its great that Zwift can find your FTP from a ride, but can't really tell if your data is questionable.
I do remember early on, seeing some people I ride with IRL, on Zwift with just amazing power numbers, knowing there was just no way. And yes, it was dumb trainers and Zwift's interpretation of power.
