Hi, I'm getting the same message when I try to download Big Sur.
Running Catalina 10.15.5
No idea what you mean with OC and do you like to see the whole EFI folder/map?

Appreciate your help

Now it is downloading.

For all those who are uncertain if their system definition will work with macOS 11 see this from Apple.

The oldest iMacs that are Big Sur Eligible are iMac 14,4 and iMac 15,1 which can also be used for those with Haswell systems.
