Cosmic Dawn Rakan's Recall is lacking sound and a post-recall landing animation?

Watching the newest skin spotlight video for Cosmic Dawn Rakan (which is presumably what the character skin will be in game), I noticed that Rakan is lacking sound fx on his recall animation and a landing animation post-recall (once he arrives in fountain). [1:08 in video if you want to see] Cosmic Dusk Xayah has both of this elements present. Is this something that may be added later or is this the way the skin is officially going to be available?

I know the SFX would have to be totally original, but the post-recall landing animation could just be recycled from his Classic skin like Xayah's is.

Additional Note: Cosmic Dawn Rakan is also missing a post-recall animation when he recalls WITH Xayah via "Lover's Leap."
