If you update your idrive software through the BMW software website, does the dealer still need to do an istep update?

It seems like all of these updates and software versions, over the air updates for regional map areas of the US, updates from BMW directly for the entire US navigation map, istep updates, and not knowing if you can update certain things on your own or if only the dealer can do it is not very clear and transparent, IMO.
I went to the BMW update site and I was presented with the following update. I'm about to install it. Wish me luck!

Software Update found: UPD09042
The Software Update is valid for BMW M550I XD, 2019

Update: No dice. Keep getting "Software on USB device incompatible with this vehicle." I've tried multiple USB drives with FAT16, FAT32, and ExDOS file formats with the same result. Of course the software version already installed on my car appears to be newer.

Current version:
Telephone: TB-006.027.001
Media: MB-006.027.001

BMW Update:
Multimedia: TB 001.062.032 & MB 001.062.040 & HB 001.062.032
