3 weeks ago Hi! @MartyG-RealSense
I have saved the calibration parameters of the same D455 camera in firmware 5.13.0.55 and 5.16.0.1:
The calibration parameters for firmware version 5.13.0.55 are as follows: "intrinsic_left.x.x": "0.493718", "intrinsic_left.x.y": "0.789467", "intrinsic_right.x.x": "0.495089", "intrinsic_right.x.y": "0.79162",
After upgrading firmware version 5.13.0.55 to version 5.16.0.1, some calibration parameters are as follows: "intrinsic_left.x.x": "0.494122", "intrinsic_left.x.y": "0.790112", "intrinsic_right.x.x": "0.495493", "intrinsic_right.x.y": "0.792267",
The above 4 parameters are the only calibration parameter differences among different firmware version. Does the camera need to be recalibrated？

Issue Description
Does the calibrated D455 need to be recalibrated after upgrading the firmware through rs-fw-update? I would like to know if upgrading from firmware 5.13.0.55 to firmware 5.16.0.1 will affect the calibration parameters.
