When building AssetBundle's using the legacy method BuildPipeline.BuildStreamedSceneAssetBundle(), using Unity 5.3.X, the created AssetBundles no longer performs Lzma compression on the AssetBundle on build platforms other than WebPlayer and WebGL.

Compression works on 5.2.4f1, 5.1.0f3, 5.2.0f3 and 5.2.2p3.
Compression fails on 5.3.0f4, 5.3.2p2 and 5.3.4f1.

Repro steps:
1. Open attached project "Legacy AssetBundles.zip".
2. Using the menu bar select "Assets/Build AssetBundle/Build Streamed Scene/Compressed" to create an AssetBundle of the scene "main" using compression. After this is created previously the progress bar would say "Performing Lzma compression", this no longer occurs.
2. Using the menu bar select "Assets/Build AssetBundle/Build Streamed Scene/Uncompressed" to create an AssetBundle of the scene "main" using BuildOptions.UncompressedAssetBundle.
3. Observe that the Compressed AssetBundle has the same size as the Uncompressed.
