Speaking only from experience (3 to 4 collections a day since the update) I’ve gotten the bonus much more frequently from Ethereals than anywhere else. I’ll get usually between 4 and 8 bonuses with every collection on Ethereal Island. I’ll get maybe 4 a day from the other five islands.

As to whether more elements means better bonus chance I have no evidence to back this up but it kinda feels like a no to me.
