I am trying to develop an ARKit iOS app. Is it possible to use Apple Watch to see a live view from ARKit (run from the parent iOS app)?
Use Apple Watch as a view finder with ARKit
You can of course send messages from iPhone to Watch. This could be an image. But I don't know it is possible to send live (animated) view.
Did you see this WWDC session ?

If I understand correctly this table, only way to have (audio) streaming is sockets to server. Could it meet your need ?
