[WebGL 1.0][URP] Material is rendered with higher smoothness value when Player is opened on Safari
How to reproduce:
1. Open the attached project's Scene labeled "SampleScene"
2. Make a WebGL build
3. Host the built WebGL Player locally
4. Open the Player on Safari
5. Observe the Material on drawn Quads
6. Open the Player on any other browser
7. Observe the Material on drawn Quads again
Expected result: Material appears the same on all browsers
Actual result: Material has a higher smoothness property value on Safari
Reproducible with: 7.7.0 (2019.4.28f1), 10.5.0 (2020.3.14f1), 11.0.0 (2021.1.14f1), 12.0.0 (2021.2.0b2, 2022.1.0a2)
Not reproducible with:
Notes:
- Tested with Safari 14.1.1
- Not reproducible with Chrome, Firefox, Opera
- Not reproducible with the built-in render pipeline
Workaround:
- Use WebGL 2.0, on Safari, enable WebGL 2.0 in Experimental settings (Develop->Experimental Features->WebGL 2.0)

Resolution Note:
Unfortunately WebGL1 is forced to use lower rendering quality settings than WebGL2 due to its limited functionality. The lower quality results in different rendering characteristics, and unfortunately will not be able to be matched with WebGL2 for the shader's lighting calculations in URP.
WebGL2 will be enabled by default on Safari 15, including iOS and iPad 15. These are scheduled to be released Fall 2021.
