I will say that the aesthetic of the machine was an afterthought.
In teardown videos, you can see that the machine layout of panels does not look different from any classic console. If I remember correctly DF called it PS3-like and I actually share the same thought that it's arrangement is no different than classic PS3.
But after the whole thing was built around it's boards, SSD, blue ray player, fans and internal case, it felt like they stood there and started thinking "ok, how can we make it look different and unique?"
Tl;Dr: PS5 aesthetic or design follow function over form excluding the white plates.
Also, no matter what color you choose , it it still ugly.
