Quadro P4000 - Does not support "WebGL EXT_sRGB Extension"

I’m on a workstation primarily utilizing Autodesk products, so I have a P4000 in my setup. I want to use a 3ds max plugin (Cl3ver) that is web based real time visualization. Unfortunately, after speaking with a tech a cl3ver, the P4000 is not compatible because it does not support “WebGL EXT_sRGB Extension”. First off, is this true? Second, if so why would this be the case when previous versions did support it? Any insights would be greatly appreciated.
