Yes, it is possible to calibrate the screen of the MacBook Pro (14-inch, M3) using a hardware device like the i1Display or similar spectroradiometers. However, it is important to note that not all calibration devices are compatible with the miniLED backlight displays found in the MacBook Pro.

For accurate calibration, you would need a device that supports miniLED backlight displays, such as the Calibrite Display Pro HL or Display Plus HL, which are specifically mentioned as capable of profiling these types of displays.

Here are the key points to consider:

- Compatibility: Ensure the calibration device is compatible with miniLED backlight displays.
- Setup: Follow the manufacturer's guidelines for setting up and using the spectroradiometer, including ensuring the display is thermally stable and the environment is controlled to minimize stray light.
- Software: Use appropriate software that supports the calibration process, such as the Calibrite Profiler.

By using a compatible device and following the correct procedures, you can fine-tune the calibration of your MacBook Pro's display to meet your specific needs.
