[2025.08] The mapping between the color represented by RGB values and how it appears on computer screen, print out, etc. can be adjusted for different purposes. 3DS Max has offered Gamma/LUT dialog that uses the simple idea of Gamma value as means to control this adjustment/compensation, especialy about brightness of the color, until recently.
3DS Max 2025 says

"3DS Max default Color Management mode changed from Gamma to OpenColoIO, using ACEScg as the rendering color space"

In this new version, the default Gamma/LUT dialog is replaced by Color Management Setting dialog, which is a more comprehensive tool, uses the idea of general mapping between two color spaces, and made on the new standard (OCIO).
With the new tool, you can select between rendering to create an image with or without a particuler color correction built-in. You can also make the image made withut color correction and apply some color correction when you view it.
