Will we see more murals in Alien Covenant?

why in the ampoule room the ampoules remain intact, neatly placed if the Engineers in panic fled to this room. if they were so they would knock them over. unless they rearrange them or from scratch. but what for? and where they fled. I think the second door from this room was where the mural of the crucified deacon was. but in another scene, is the pile of engineers' corpses by the door the back door to the ampoule room? you can see that the bodies were torn apart as if it was a black goo, as in Covenant or during the intro of Prometheus. So why, after being infected, would put these ampoules back on the spot, as if they had set a trap, but who and from whom were they escaping? How did the Black goo flow out of the ampoules if it was still inside the glass ampoules as shown by David.
