Field test mode for Windows 10 PC?

I know the old tricks for enabling field test mode (I want to see actual signal strength in dB) on Windows Phone 8.1. But none of these seem to work on Windows 10 Mobile.

This applies to both an old Lumia 1020 that has been running the Insider Preview and my new Lumia 950 (both unlocked).

Has anyone figured out how to access Field Test Mode on Windows 10 Mobile yet?

    Unlike Windows Phone 8.1, the classic *#*#4636#*#* code (for Android) or similar USSD codes don't reliably work on Windows 10 Mobile. Some users have tried dialing specific secret codes, but most of these don't work anymore or are unsupported.
