U2724DE firmware update M3T103 - firmware not for this monitor

Hello :)

I have a problem with firmware upgrade. Got the latest firmware from dell U2724DE support website and tried to install it - getting this error. 

- Windows 11 ENG (Ryzen 5 7500F AM5 + Radeon 5600XT + latest windows updates) tried to run as administrator and not as administrator

- I only have (as instructed) connected: USB-C from monitor to PC (the cable that came with the monitor) + power cable + DisplayPort cable

- Tried the same process with Macbook Pro 2019 - downloaded the MacOS firmware update package - connected through Thunderbolt only - and getting the exactly same error message on MacOS.

Posting error message screenshot + my monitor info.

Am i doing something wrong? Or should i just avoid the firmware upgrade? Anybody facing the same problem?
