...and?
In the uncompressed case, you take some data on disk and copy it to the
framebuffer. In the compressed case, you take some data on disk, copy it
to RAM, perform a vast amount of highly compute-intensive work on it,
and *then* copy it to the framebuffer. Obviously the latter shouldn't
use less CPU power than the former.
