Hi Donny,
It’s not a shine finish, think it may be a weird lighting reflection.
The keyboard looks great, no gaudy white buttons like on my  psrs 950, looks less toy like.
Looks better than my PA3x too.
Has a recessed back where all the bits plug in, makes it simple to see what you’re plugging and unplugging. 
Haven’t had a chance to watch the above video yet, so Woody might have mentioned it to.
Btw to me the screen has a firm feel.
