I have a theory that we will see Bloomix again in the future episodes...

I think that when they are not entering the Legenderium and they are having a fight with the Season 6 Villains, they transform into Bloomix. But when they do enter the Legenderium, they transform to Mythix... (Possibly, we won't see Mythix in 2D)

Proof: See the Video "Thank you all, fairies!" There are 2 (I think) scenes that the Winx are in the  Bloomix form and those scenes weren't release with the episodes we seen. For example, at the end you see Stella and Bloom high fiving, and it looks like the setting is from the Caribbean (I think).
