Shadow Magnezone changed :( why?

Shadow Magnezone used to look like this:

Like an angry, scary, bright red light. The red in its eyes was actually emitting soft light like a night lamp. It was so cool. Now it lost the red light in its center eye completely and other eyes are just…flat red. Not light-emitting. Flat red like all other shadow mons.

Why? Change it back pls Niantic.
