I can almost see it that way when looking at single plates like that one in isolation, but when viewed as a whole I just can’t see them all that way.
Viewing it as convex puts it at a weird, almost floating angle relative to the other plates, which my mind tells me cannot be the case if they’re all supposed to be laying flat on a table. The camera angle being what it is, I’d expect to be seeing more of the illuminated left half than the shaded right half if it was truly upside down and laying flat. Not to mention the shadow basically touching the embossed oval shape on the right, while the left has a bit of a gap between the oval and the start of the bevel of the plate edge, indicates that the light would be coming from the right rather than the left (because shadows can extend), unless the plate is supposed to be oddly asymmetrical or something.
