"WebTexture storage is uniform; all pixels have the same number of channels. Even if a specific pixel has an alpha of 0, it still stores RGB values as well. Though some image editors/file formats may not bother to remember the RGB values of invisible pixels, so in some cases you can see that invisible color get wiped out (usually replaced with black).
