DJI Goggle 2 FCC HACK Penetration Test

FCC Hack on the Goggle 2 provides more channels and increase in RF transmission power compared to CE mode. But if you already live in a FCC region, does the FCC Hack beneficial except for proving more channels while infmanual mode. I did a penetration test comparing the Goggle 2 transmission on Auto and Manual. You let me know if you can see a major difference on transmisson quality in Auto Vs Manual
