Canon WBInfo tag - wrong names for all subtags?

[drcq]

Hi,
looking at Canon images with WBInfo tag (in MakerNotes) I recognized that all subtag names starts with WB_GRGBLevel which should mean "White Balance Green-Red-Green-Blue Level",
but the shown values (like 850 1839 1596 850) don't fit with this name. The first and last value are always the same.
I checked it with PowerShot G9 images.

Christoph

Thanks.  I'll look into this.
