Interesting magic word. My prompts were often full of 'masterpiece' or 'octane render' (which improves 3D consistency).
With regard to your main point, I generated more than a thousand images trough various models, and yes good results such as these posted on social media are very rare. And people definitely spend lots of time to adjust things with inpainting and other tricks, in a way that I would find infuriating. For the effort it takes I would rather just redraw it. It depends on the styles; with brushstrokes you can hide a lot, with cartoon lineart is crucial so fixing requires more work.
