Description
When I compared the zipped and unzipped versions of an h5ad file (e.g., TCGA-KK-A59Y-01Z-00-DX1.0DB9AF4D-4879-4295-A321-CBEE0FE6B2A0.h5ad.gz), the files were the same size (67.2MB). Isn't the zipped version supposed to be smaller? Can you check? Thanks!

Research direction
Start by reproducing the size comparison using the named TCGA-KK-A59Y-01Z-00-DX1.0DB9AF4D-4879-4295-A321-CBEE0FE6B2A0.h5ad.gz file and inspect the repository entry point that creates or compresses h5ad files. Done means identifying why the compressed and uncompressed files have the same size and documenting or correcting that behavior.
