    | Feature | CUBE (3D LUT) | XMP (Adobe Profile) | | :--- | :--- | :--- | | | Absolute RGB values | Relative to RAW development sliders | | Hue Shifts | Perfect (e.g., Teal shadows, Orange highlights) | Good (uses 3x3 matrix + curves, less precise) | | Saturation | 3D saturation mapping | 2D saturation curves | | Gamma Handling | Stores exact gamma curve | Relies on Adobe’s Process Version (PV) | Challenges and Considerations
