yes there is.

not always.

cmyk is 32bpp or 64bpp with four components per pixel, none of which
are transparency. for hexachrome, there's 6 components per pixel. 

you're also assuming each component is one byte. that's no longer true
(and hasn't been for years). most modern apps use 2 bytes per component
(48bpp or 64bpp) or floating point components.

it's much more than just that.
