Mostly opinions here but i think that mastered UI is a lazy design but super has been lazy in general (the anime atleast the manga is nice) its like look his hair is red, cool is blue, now its white arent you amazed? But the concept is cool i guess
As we see in the first DBS saga, Goku gains a new form, the SSG form, which keeps him in like he is in his base form with red hair. It's exactly the same with MUI. Toriyama wanted to keep him like he is in his base form, in order to state that Goku also became a god, even surpassing some Gods of Destruction. First we see him in his base form with incomplete UI, but in the end we see him with white hair, the only logical and most suitable color to make us understand that he has become now a deity.
