Bathroom - silicone between tiled wall and ceiling?

Hi there, title says it all. Recently had the bathroom done up, i can't say the tiler was the best (I had to silicone the vertical corners for example).

I've noticed the joint between the ceiling and tiled walls isn't sealed either, should it be? I would assume there's a likelihood of moisture ingress from the shower? And if it needs it, just regular silicone? Thanks

Edit it seems like decorators caulk could be enough?
