Samsung TV remote not working with TV when RPi is active

What makes you believe it does NOT have CEC. A TV manufactured in 2014 without CEC is very unlikely I have a TCL Roku Smart TV (purchased in November) and only has very basic CEC support. It does not pass any keypresses from the remote to the Pi. It only seems to support detection of connected devices.
