You have referenced and asked for scale many times, that this fails you just cements why I posted that. It’s the same reason all of your examples about bodies of water fall so short. Do you realize how limited the scope of any camera, laser level that exists are? There is nothing that could measure a blip on the surface of the ocean, of course you won’t see curvature. It would be the same thing if you could imagine a quark sized camera trying to do so over that drop of water.
