Looking at the source code, it appears that exiftool is calling the same tag list as with any other Olympus Makernotes.
Compare MakerNoteOlympus (https://github.com/exiftool/exiftool/blob/8afb211a87b435411e124caccbb4565f881bd3a5/lib/Image/ExifTool/MakerNotes.pm#L551) with MakerNoteOlympus2 and MakerNoteOlympus3, the latter of which appears to be for the OM SYSTEM ID.  They all call
TagTable => 'Image::ExifTool::Olympus::Main

There may be nothing new, just a different format maybe?  But they should be on the Olympus tags page (https://exiftool.org/TagNames/Olympus.html), I would think.

Using Archive.org to compare the Olympus page before and after ver 12.41 (https://web.archive.org/web/diff/20220308053041/20220419134750/https://exiftool.org/TagNames/Olympus.html) shows the only change was the addition of 'S0095'= OM-1 to the Olympus CameraType Values list.

They changed the makernote header, but the tags were the same as with other models.
