A professional GUI requires quite a lot. A Unity expert can correct me, but IIRC (possibly wrongly) at least the following limitations apply: For example Unity does not have accessibility features (screen readers etc) nor I don’t think it’s DPI aware. I would _guess_ it does not support platform fonts. Not sure if it supports non-latin font layouts like arabic. Etc etc.
