Isn't color depth about the color itself? I guess alpha wouldn't apply
in this case.

In the same format list:
  - RGB565 has a depth of 16
  - XRGB8888 has a depth of 24
  - XRGB2101010 has a depth of 30
  - ARGB8888 has a depth of 32

Which seems to indicate that the list indeed meant that the color
depth is about the color, and that ARGB8888 is wrong.
