seems PS, no scaffoldings, grey paint, and suspicious red pillar (probably port crane pillar from other ship pic in port)
Actually, there is scaffolding (just not that much because the ship is in early stages of construction -- no mast or sensors for scaffolding yet), and the grey paint is not suspicious at all (modular construction means some parts are painted earlier than others, we see that with the 054A mast often).
However the red pillar is an indication it could/likely/almost certainly a PS(?). If you compare the pillar with the one in this picture, almost everything looks the same. The below pic is probably what it was psed from?
going through previous pics, I take back what I said about the smoke stacks -- one is a smoke stack, the other is the mast lol. For some reason I always thought the mast was the red stump
