I have the BRIO 4K Pro webcam. A few months ago, I downloaded firmware version 2.7 for it, which I could have sworn was linked on it's support page. However, the firmware listed there is the older 2.2 version dated 2019-04-29: https://support.logi.com/hc/en-us/articles/360024703494--Downloads-BRIO-4K-Pro-Webcam

It appears that I actually downloaded the firmware for the Ultra HD Pro Business camera which is now up to version 2.9, dated 2022-03-23 here: https://prosupport.logi.com/hc/en-us/articles/360039591834-Download-BRIO-Ultra-HD-Pro-Business-Webcam

Now the thing is, version 2.7 upgraded the webcam and I have had no problems with it. With firmware downloaded from either support page (2.2, 2.7, 2.9), they all identify the webcam as the same model. So, is it OK to use the newer firmware from the HD Pro Business page for the 4K Pro even though it is not on the support page for it?
