I think I threw up a little...

It does make me wonder if they changed something more minor (e.g. added pathway or software that is on the N63TU) at some point or maybe it takes a bit to start working?

Now I need to search if other M5 owners have this working or not...

I picked my September production M5 at a dealer and cancelled my December production (that just went into production) which is why I threw up a little when I started researching this technical upgrade (TU). If it is just software or an added pathway, no big deal.
I was referring to the new N63B44TU, and yes your M5 has the S63B44TU.

We know that Sport Displays work in the N55B30 used in the F10 535i, and the new N63B44TU used in the F06 650i GC, but they do not work in the older N63B44 used in the F10 550i, the F12 650i, and the F07 550i GT.

I find it odd though that the updated version of the N63B44 was made to support Sport Displays, but the updated version of the S63B44 seemingly was not. Maybe BMW just does not want Sport Displays working in the M5/M6.
