Stream Deck Scissors dim and tinted yellow?

I have three Stream Decks - a Neo, a regular (15-key) and a new scissors (15-key). The Neo and regular are both bright with white whites. The Scissors model is a lot less bright, and the white is slightly yellow or khaki. Even though I have its brightness set max, and the other two aren't.

Before I consider it defective, I'm wondering if this is just a side-effect of the different mechanism for the scissor keys.

Anyone else notice a difference?
