Answer 1

Isn't this just a mix in the order of the color components?

I'm not familiar with any of these functions, but I believe that DIB_RGB_COLORS gives you the components in the “blue, green, red, reserved” order, whereas TYPE_4BYTE_ABGR is expecting the components in the “alpha, blue, green, red” order.
