The visible damage to the frame looks repairable, i.e. repair job on the outside face of the frame using a lot of prep work, application of epoxy-wetted patches of carbon weave, and a lot of tidy up. Then perhaps a massive sticker over the top if you don't want to paint it. :D. I have performed a repair like that before on a race bike top tube.
However, the fact this was caused by the seatpost clamp is more worrying and suggests potential damage from inside the seat tube and that is something I've never fixed before.
Out of interest, is/was there any carbon assembly paste on the seat post?
