OK, here's the mystery. You showed me the WinPE produced after the HBS build of your ISO. I actually looked at the contents of the OPE files delivered (using 7z as well). 7z shows both OPEs (delivered by the two different downloaders) as Win10-based... kinda weird.
I then let HBS build its WinPE through the Emergency Disk process (twice using two different installations) and VOILA, the one produced by the downloader marked "latest" indeed produced a Win11-based WinPE, even though 7z showed its OPE contents to be Win10. The one produced by the v2 downloader produced a Win10-based WinPE.
I have no idea why 7z showed the OPE contents to be Win10 when it produces a Win11 WinPE via HBS.
I would suggest renaming your downloaders accordingly (to avoid confusion)... "v2" & "Latest" don't really coordinate well... maybe indicate the Base WIM being used to produce it.
As far as the OPE files and 7z... take a quick look yourself, maybe just to measure my sanity a bit
This is most likely a 7z issue of some sort when looking at OPE files.
