Looking at one of these failures (reading js.zr/blosc/lz4/ with Zarr) the first few values differ:
Yeah, the values seen there are what would be obtained when trying to convert uint8 values to int8 so that values >=128 overflow and become negative.
uint8
int8
For example
import numpy as np np.asarray([154, 147, 151, 109], dtype=np.int8)
gives
array([-102, -109, -105, 109], dtype=int8)
