Well if you want reflections like that object, it needs to be shaped like that, it needs smooth, more-or-less constant double curvature while what you’ve got is closer to a fillet between 2 straight surfaces, so the reflections are just going to do that. Now also remember that those Emap enviroment maps aren’t not high-resolution by modern HDRI environment standards, and you have the analysis meshes set to maximum coarseness, so I don’t know that what you’re worried about isn’t mostly just artifacts from that.
Well the surface quality of it seems alright for rendering, you should do an actual test render with a high-resolution environment. This is getting to very subjective territory here, I’m not sure how you expect a shape that’s nothing like a blob to have the same reflections as a blob.
