With all due respect, house, if you look at a blow up of the relevant area you can see clearly that it is NOT a raised triangular area. It is definitely a notch as shown below (again):
In addition (something which I don't believe has attracted as much attention) there is a clear separation between the screen surround and the body. That separation line runs into the notch. This tells me there is something different here. Exactly what that is, I don't know. But for some reason the screen is not integrated flush with the body and there is a small cut out at the bottom right.
On my K3 and K10D the screen finished flush with the body.
