You pretty much answered your own question...

911 + GT3 CUP = 911 GT3 CUP

Have I? Let me quote myself - with underlining:

"I can tell by checking Race Results that it's a 911 but I don't know whether it's from official DLC or freely downloadable. Nor whether, when I do have the correct car installed, the app will recognize it or insist I need the Tatuus."

I am assuming that just any old 911 download won't do. It has to be the exact one everyone else has yes?

So no... the questions still stand.
