Confirmed too on my IN2020, this is great (Art)work, kevkid, thanks!
Just one small thing; I had to clear camera's cache and storage data to finally have photochrom option appear. Without this final step, it wouldn't. Seems obvious but maybe not for everyone, so you may want to add it as a final step in your instructions maybe.
Also had to use an adb terminal emulator Android app, and not computer's adb terminal, to have access to the props through that module and be able to edit them.
Wish there was such an easy way to get back to Widevine-L1 after bootloader's unlocked...
