Delta encoding is a lossy compression.

Why is it lossy?

Here is the example from wikipedia:

Perhaps the simplest example is storing values of bytes as differences (deltas) between sequential values, rather than the values themselves. So, instead of 2, 4, 6, 9, 7, we would store 2, 2, 2, 3, −2. This reduces the variance (range) of the values when neighbor samples are correlated, enabling a lower bit usage for the same data.

Surely you can recover the sequence 2, 4, 6, 9, 7 perfectly from 2, 2, 2, 3, −2. No?
