I only have X-Rite i1 Display Pro and I will use Calman 5 or HCFR so I can't use the Autocal.If you have a Spyder 5 you can just use gamma Autocal to correct the gamma droop.
For manual calibration, Correction Value simply copies the selected gamma to the custom slot. If the gamma is too low overall when using Normal (2.2) you can select a higher value such as 2.4, and use the Picture Tone etc to fine-tune it, as described in the owner”s manual:

If the three ranges are not sufficient, you can use the 12 point gamma adjustment option in the JVC autocal software.
