(1)The BMW-packaged fluid as well as the VW-packaged fluid are both the exact same thing. The fluid inside is blended by a Mobil subsidiary and marketed as ESSO LT71141. Remember, when I say VW, I mean VW dealerships, not online places selling a "VW tranny fluid". The LT71141 fluid is a amber (almost the same as motor oil) colored fluid. The ESSO fluid is a semi-synthetic fluid derived from Group III basestocks with appropriate additives and friction modifiers. This exact fluid is also sold directly by ZF (around $13/litre) and by Audi/Porsche/Jaguar and Volvo dealerships.
(2) VW also publishes a spec for its tranny fluid and up until last year, ESSO was the only one marketing a fluid meeting that spec. Then Pentosin also started marketing its ATF1 product as meeting the relevant VW spec. This is NOT and NEVER WAS the OEM VW fluid. This fluid is also amber and is a semi-synthetic. Nothing else can be known for sure about this fluid. I would not waste my money on this fluid, which is generally available from online suppliers marketing VW parts.
(3) Then there are synthetic fluids like Redline, Mobil1 etc and IMHO, there isn't adequate field experience to support the application. Redline recommends their fluid but they aren't much trustworthy or technically competent. Mobil1 is a great product but Mobil doesn't recommend using the fluid in the application.
(4) Finally there are semi-synth fluids like Pennzoil/Quaker State Multi-vehicle ATF and the Valvoline MaxLife ATF, both of which claim that the product is correct for the application. However, Valvoline admits it hasn't done "exhaustive testing" in these transmissions and Pennzoil shows clearly inferior flash point data so I very much doubt its suitability for the application.
I would either use the VW-marketed ESSO fluid or would use one of the other fluids knowing that you do so at your own risk!!"
Anyone want to chime in?

why is it so damn hard to just get BMW transmission oil without paying stealership price....

Unfortunately, being in an apartment setting and all, my tools are limited, and my knowledge (past plug and play mods like my intake) is limited as well. Regardless, thanks for sharing your knowledge with the rest of us. I applaud you for meticulously maintaining your car
