[ #1 ]

The OCIO implement still get issue with display in viewport, current solution is using custom GL Function to evaluate the OCIO color in viewport

The custom GL evaluate OCIO shader in viewport that color still not match color in maya

Color algorithm or GL shader not evaluate correct color
Use native color correct parameter in UsdImagingGLRenderParams in UsdImagingGLRender

UsdImagingGLRenderParams &params;
params.colorCorrectionMode;
params.ocioDisplay;
params.ocioView;
params.ocioColorSpace;
params.ocioLook;
