S7 Edge firmware

On my S7 Edge I downgraded to Marshmallow using Sam Mobile and Odin.
My product code is EVR (EE) UK. But my phone is unlocked...

I downloaded the latest one the United Kingdom latest security patch December.
Build Number: G935FFXXU1BPL2. Apparently this firmware version is BTU which is the one directly from Samsung.

Will I get future OTA updates?
Right now I'm unsure to go back to original firmware or stay with the one now.
