Before starting the grayscale adjustments, take a 21-Point Grayscale run measuring all display available gamma presets, then view the reports and choose to work with the one that you see that is measures closer to your target gamma (so you save time from less adjustments which will be required to fix the issues later).
Do the same test with colorspace preset (taking 4-Point Saturation sweeps....choose the one that has better tracking of REC.709) and do the same with Color Temp preset (taking 21-Point Grayscale....choose the one that has less RGB errors in average, to see which mode is closer to D65).
BTE, to the HCFR. fo to HCFR Preferences -> Advanced -> change the Grayscale handling to ''Absolute Y w/gamma'', to include to the dE calculation the gamma errors also. (Color Difference Formula from Recommend to CIE2000)
Look at each % Grey data the meter reports, there is a Y (which shows to you the measured luminance) and the Y target (which show the target luminance), and re-adjust your settings to fix gamma errors also.
When you will find all these, you will do contrast/brightness/color clipping check via patterns and after that you will start to calibrate your grayscale. Start with 2-Point RGB balance and do 100% White with RGB-Gain and 30% Gray with RGB-Offeset controls, when you will do many back/forth until you have stable readings, you will move to 10-Point RGB balance, after your are ready with grayscale you will move to CMS calibration.
When you will start with 100% White, keep one of the R or G or B at zero position and reduce values from other 2 controls, while to handle your luminance output (nits) you will use the backlight (not the RGB balance controls).
If you have 10-Point RGB balance controls, its better idea to use 21-Point Grayscale patterns, its better for detecting un-align of calibration controls adjustments with displayed xx% patterns.
Also a good approach is to not perform static pattern real-time (with TV menus active, that can affect your measurements), but to run a complete grayscale sweep and then look your charts and apply at once all the settings per each control you believe that will fix (reduce) the errors, then run a new grayscale sweep and you will see that your errors will be lower now, then repeat-repeat until the results will be good.
After the end of grayscale you will move to CMS calibration, after the end of CMS cal, re-check grayscale again.
For SDR REC.709 calibration you have to use patterns designed for REC.709 and compatible with HCFR color engine.
For example, the AVSHD you are using, it has a mismatch to grayscale patterns (see more details reading the ''3'' here
), this can be fixed from inside HCFR with a software offset, see here what you can do to fix the issue: LG 2017 OLED Calibration Thread and Settings
Also the 4-Point Saturation of AVSHD is not compatible with HCFR (and there no fix about this), for example:
AVSHD 50% Red Saturation Pattern has RGB Triplet 190.95.95 but HCFR's Color Engine needs/calculates errors from RGB Triplet 191.96.96, it's 0.42 dE2000 error.
AVSHD 75% Magenta Saturation Pattern has RGB Triplet 203.100.203 but HCFR's Color Engine needs/calculates errors from RGB Triplet 202.99.202, it's 0.36 dE2000 error.
