Steps to reproduce:
1. Open Cannon Fodder style game project (Link in edit field)
1.1 Put all the content from the "Whitebox" scenes into a single one for easier building
2. Build with Default, LZ4 and LZ4HC Player compression in build settings
3. Launch and compare each apk time till scene was loaded

Expected (According to docs):
LZ4 and LZ4HC are supposed to open faster than Default;

Actual:
3D Cannon Fodder game - LZ4 and LZ4HC take significantly longer to open than Default (Test results at the bottom of this case)
