[Bug]: Color rendering and transparent backface issues on mobile (vs PC)

### Platform
Mobile (iOS and Android)

### App Version
Not specified

### Device Information

### Issue Description
Two rendering inconsistencies observed on mobile compared to PC client:

1. **Colors appear too red**: Materials/textures display with incorrect color saturation - appearing overly red on mobile while rendering correctly on PC
2. **Transparent backface rendering issue**: Transparent backfaces not rendering correctly on mobile (work as expected on PC)

### Expected Behavior
- Colors and material saturation should match PC client rendering
- Transparent backfaces should render consistently across mobile and desktop platforms

### Steps to Reproduce
1. Load scene on PC client - observe correct color rendering and transparent backface behavior
2. Load same scene on mobile device
3. Compare rendering output - notice colors appear too red and transparent backfaces render incorrectly
