As expected, no hardware fix. Not only is the orientation the same, but all chips on the driver board are identical.
If Apple was going to fix it, they would have stated it clearly, not hide behind some ambiguous language.
Repost from my comment last week: If you look at a teardown of iPad mini 6, you’ll see the display controller is attached to the long edge of the display assembly. There is space carved out in the chassis to accommodate it. To rotate the controller would require completely laying out the battery and logic board design again. There was no chance that was going to happen.
