Google changed the description with the November-Update today and it seems that they've mixed it up previously.

So the current regional versions are:

RD1A.200810.020, Oct 2020, AU & JP carriers
RD1A.200810.020.A1, Oct 2020, KDDI only
RD1A.200810.021.A1, Oct 2020, EU carriers
RD1A.200810.021.B3, Oct 2020, Verizon
RD1A.200810.022.A4, Oct 2020 (global?)

RD1A.201105.003, Nov 2020, JP carriers
RD1A.201105.003.A1, Nov 2020, AU carriers
RD1A.201105.003.B1, Nov 2020, EU carriers
RD1A.201105.003.C1, Nov 2020 (global?)

Anyway. As said, I bought my Pixel 5 from the german google store and not from a german carriers store. So I expect to be on "RD1A.201105.003.C1" instead my phone updated to "RD1A.201105.003.B1".

Still confusing but at least the "KDDI only" - discussion is solved. I guess. ?

Isn't the C1 version for the US carriers? That's probably the firmware/image file that has support for the mmWave hardware in the US models.

The OTA Images download page lists two images.
One normal one, and one "KDDI only".
What exactly is KDDI? My take from Googling it is that it's some Provider.

The device I got came with said "KDDI only" Image on it (Build Number ends with ...021.A1), and VoLTE and VoWiFi aren't working, and I somehow suspect it might be the wrong image.
Makes me wonder if I can just sideload the non-KDDI OTA image to fix it? Anyone happens to have any insight there?

Edit: Just sideloading the non-KDDI OTA image does not work. Downgrade-Prevention kicks in.
Got December security patch my build number has no kddi next to it am in uk where or how to find out if its kddi or not
