I zoomed into the photo to check that out after you pointed it out. I initially assumed it would've been placeholders that were labeled, since writing `DISPLAY` on your screen doesn't make sense, but the buttons and MicroSD slot are obviously there. The text for the MicroSD slot extends past the edge of the front surface, though, so it's not actually physically labeled-- just labeled in the image with a perspective effect. I assume it's because the buttons are a bit hard to see (and it's not obvious the display is a display without it being turned on).
