There is no way to specify compression in asset packs, so this is by design.
Reproduction steps:
1. Open the attached project “ReproProject”
2. Download bundleTool from https://github.com/google/bundletool
3. Open the “Player Settings > Player > Publishing Settings” menu and select “Split Application Binary”
4. Open the ‘File > Build Settings’ menu
5. Choose "Build App Bundle (Google Play)" and set the Compression Method to 'Default.' Start building the Project
6. Use the Terminal to navigate to the Build Folder. Enter: "java jar bundletool-all<bundletool version>.jar build-apks --bundle=<build name>.aab --output=repro.apks”
7. Open “repro.apks” with an extraction tool/ in Terminal
8. Go to the “asset-slices” folder
9. Unzip “UnityDataAsset-master.apk” in the Terminal with the command “unzip -v <apkname>.apk”
10. Proceed to the "assets > bin > Data" directory and observe the compression status of the files
Expected result: The assets are Compressed and have the Method “Deflate”
Actual result: The assets are not Compressed and have the Method “Stored”
