All these test produce diff.png in build folder and all of them show visible saturation difference in color. Attached expected, generated and diff image for once such test. This is observed in macOS 14.6.1 machine while verifying metal implementation.

This color difference can be seen in both OpenGL and Metal pipeline in macOS.
