[tvOS] Corridor Lighting Example project is not working on AppleTV with Metal & OpenGLES3

Steps to reproduce:

1. Open new Unity project and download 'Corridor Lighting Example' from Asset Store (or Open attached project)
2. Switch to AppleTV
3. Make sure 'Graphics API' is set to Metal or OpenGLES3
4. Build to AppleTV
5. Notice almost entire screen is black and nothing is rendered correctly

This seems to be caused by 'Bloom' image effect that is attached to 'Main Camera' game object. Disabling 'Gloom' script prevents the issue.

Issue does not occur on iOS. Also works correctly on AppleTV with OpenGLES2.
