Late 2013 27' iMac = Supported or not?

[Lz0]

My 2013 27' iMac, 3.2 GHz Core i5 isn't in the list of compatible Mac's for Big Sur but if I go to the Big Sur download page on the App Store it tells me it is compatible.

So do I try an update to Big Sur or not?

I have the same imac14,2 with fusion drive and have found this on reasoning it is the Thunderbolt 1 (not TB2)

The Reason Apple dropped iMac14,2 from Big Sur Supported Macs

II When Apple announced which Macs would still be supported by macOS 11, I found it hard to believe they dropped support for 2013 iMacs and kept support for the 2013 MBP and 2013 Mac Pro. There seemed to be no good reason to drop the Late 2013 iMac from their list of supported Macs. It's more...

and also the following surmises that the performace on this fusion drive was reported to be poor with Big Sur:

Supported Macs - Patched Sur

Which unsupported Macs are supported. How can they be both? They are unsupported according to Apple, supported according to me. Thanks to BarryKN for originally compiling this.

I don't know, but please let us know your experience if you give it a try and also if you needed to patch anything to get by 'unsupported' or if the App store just goes ahead and installs. I see the same "Works with this Mac" under the Compatiblily on the App store page.
