Calibration != Profiling While most cards have per channel Luts, none will have per rendering context 3D color transforms (although it can be simulated using 3D texture lookups). Rendering context is usually somewhere up the rendering stack though, not something the hardware will be directly aware of. (It's rendering context because the transform depends on the source colorspace & intent as well as the display profile. In general it's not a 3x3 matrix transform either.)
