Color Management Preferences(Previously Gamma and LUT) has two new OpenColorIO v2 based color management mode 'Gamma Workflow' mode will give you the same behavior as the 'Enable Gamma/LUT Correction' checked. 'Unmanaged' mode will give you the same behavior as the 'Enable Gamma/LUT Correction' unchecked. The previous workflow is provided as an optional mode.

Everything should work exactly same as before. The highest priority was not breaking the existing workflows or existing scenes while providing the brand-new workflow. Old gamma manager and colorcorrection manager classes are being deprecated, new ColorPipelineMgr will provide unified interface for both the legacy gamma workflow and OCIO-based modern color management workflow. Also color processing pathways, including few API exposed areas were modernized to make sure color fidelity is retained throughout the system. Until 2024 3ds max has assumed color spaces with sRGB primaries and provided color management via de-gamma/re-gamma workflow.That sRGB assumption removed.
