Nothing valuable that I've seen. Tested for eARC and it's not there. Not sure why Samsung engineers are wasting their time updating the web browser in the TV. Seems like the Engineering lead (or whoever prioritizes requirements) should be fired.
The notes from the update say:
Improved usability 1. Improved browser performance 2. Improved app performance 3. Improved stability 4. Improved usability of input devices
My q70r also doesn't see any new update over the air, same when I plug the USB drive with the firmware unzipped (I managed to download it from Samsung's Download Center - around 1.4GB). So I'm not sure how is it compatible with 2019 QLED line - my model was included in the firmware's notes. So I'm still on v.1361.
I managed to install v1371 from USB. I needed to make sure I'm using a package called T-MSMDEUC (probably related with geographical region?). Previously I downloaded T-MSMAKUC which my TV couldn't identify.
