I have a theory on how a semblance can be upgraded. since each one is a fairly simle basc power and doesn't leave much room for improvement besides by increasing aura volume and control. My theory is this. if a person has a significant personal change, it can become more powerful and visually different.

Using blake as an example, initilly her shadow semblance merely ejected her before fading away.

However, after she came to terms with her time in the white fang, decided not to let it define her, and to stop running away, it changed quite a bit. Keep in mind, there was no black or purple dust in the clip, meaning this was pure semblance.

make of that what you will, but i simply say: headcanon accepted
