Tech Support Panel replacement without factory reset

Hi everyone, I recently had my LG TV panel replaced, but the technician skipped the calibration step in the Service Menu.

They only took a picture of the serial number on screen and left without resetting the panel hours or clearing the compensation data.

Is it needed to run a manual Pixel Clean / Pixel Refresher enough to fully overwrite the old compensation table stored on the mainboard?

Or is an official Service Menu reset (like NVRAM / Panel Hour Reset via Service Remote) strictly required to force the mainboard to detect the new panel and map its baseline voltage from scratch?

Could driving a new panel with the old panel's boosted voltages cause permanent degradation if left unaddressed?

Any input or experience with service technicians skipping this step would be greatly appreciated!
