I think the film is attractive. I'm disappointed that they've muted the color range in so many sequences, but it still has an elegant look.
That said, the Day of the Dead scene was always intended to look stark and menacing. The dominant colors on set were black and white with slight color accents. Van Hoytema may have bathed it all in a dusty haze (probably to evoke a sense of heat), but it was never going to "pop," even if Deakins had been behind the camera.
It would take Meheux for that.
