Various encoders Razer deathadder v3 pro

Having two new mice (black and white), I discovered that they have different encoders.
The white mouse has a KAILH encoder.
The black mouse has a RAESHA encoder.
In the white mouse, the wheel rattles and the cutoffs are not clear, in the black one, the cutoffs are clear and there is no rattle
I also found different finishes.
The white one has matte and rough plastic.
The black one has matte and smooth plastic.

Razer, I'm disappointed
I demand an explanation as to why one of my mice seems to be defective.
