URP Sample's Pixelate.shadergraph Custom Node uses unnecessary One Minus Node which creates artifacts in the Scene when using OpenGL Graphics API

Steps to reproduce:

1. Create a URP Sample Project from Hub
2. In Project Settings > Player switch Graphics API to OpenGLES 2/3 or OpenGLCore
3. Open Scene "TerminalScene" and enter Play Mode
4. Move straight until you enter the room and the "OasisScene" is loaded
5. Observe the screen where the loaded Scene should be displayed

 

Actual results: The Scene displayed in the screen is inverted and leaves graphical artifacts when looked at as the custom node uses an unnecessary One Minus Node

Expected results: The Pixelate.shadergraph Custom Node works with all Graphics APIs

Reproducible with versions: 6000.0.73f1, 6000.3.14f1, 6000.4.4f1, 6000.5.0b5, 6000.6.0a3

Tested on (OS): Windows 11, Ubuntu 24.04
