Not quite. Delta of deltas means that periodic timestamps turn into a long run of zeros (since the difference between each point is constant), which is very easy to compress. In the Gorilla paper, 96% of timestamps compress down to zero, which is encoded by a single zero bit. For series without periodic sampling, delta-of-deltas performs similarly to normal deltas.
