Are there different classes of 32-bit color, perhaps "real 32-bit" and "faked/faux 32-bit"?

I am working on a 16x16 icon for the Windows XP system tray area (in
the lower right corner) and I noticed that if the artist sends me a
*.ico in 32-bit color:

 - MS Visual Studio complains that it cannot *edit* 32-bit color
(which is fine, and reassuring)

but most importantly:

 - The icon looks much nicer (*) than if I use 24-bit color.

The doubt that I have is about IrfanView: it claims that the file in
question is only 24-bit color.

Is there anything about 32-bit color I should know?

TIA,

-Ramon

(*) The staircase lines are gone: it looks like the extra depth info
is used to render the 2D image.
