They were then fitted with Club Suites, had the IFE upgrade and had their configuration changed to match the other GE-772s at LHR.
This isn't quite correct: all of the LGW 772s were upgraded to eX3 IFE during their original refurbs in 2018 & 2019 (well, and 2022 in the case of YMMA). When those 3 were converted from 77R to 77M layout they would have had to have had their IFE
downgraded to align with the rest of the LHR 77Ms, and even BA recognised that this would be bonkers so they retained the eX3 installation. So now there's 3x 4-class LHR 772s with better IFE than their peers, though the Thales system on them is fine really.
