Is this normal?

It's an Xbox One X, simply posting to say I've seen the best way the black trim appears to have "drooped" a bit, barely curved downwards within the center, it's presently sitting on high of my laptop computer within the image, however in any other case it's on a stable flat floor subsequent to the TV, and it's elevated by some 5g wheel weights on every nook as I've been instructed numerous occasions that elevating it up even by a number of millimetres can enhance airflow beneath it, the entrance and sides appear roughly straight, it's simply the again of it that appears slight curved down, simply wish to know if it is a concern or if it's nothing to fret about.
