A guide to figuring out the voltage range supported by any electronic equipment -by looking at the power cable

UN65ES6550F Can I Run The TVs Power Cable Through The Wall

Samsungs TV's power cables are UL (Underwriters Labs) certified but are not CL (In-wall) rated. A CL rating on a cable (CL2 up to 150 volts, CL3 up to 300 volts) means these cables have a slow burning outer jacket that should meet the fire codes and are safe for in wall installations. Since the power cord for the TV is not CL rated it should never be installed inside a wall.
