Some artifacts with soft baked shadows can be observed when the platform is switched to mobile. Texture type format is converted from RGBA Half to RGBA 32-bit for mobile platforms due to compression reasons. Manually, texture format can be switched to RGB 24 by setting Texture Type as Lightmap in the inspector, however this makes the texture less bright. This is only a issue when the mixed lighting is used.

Steps for reproduction:
1) Download the project "Statics" attached below.
2) Ensure that build target is switched to Android/iOS
3) Open the scene "Statics" and generate the lighting
4) Observe the bug

Notes:
- Issue introduced with light modes (5.6.0b2)
