Would a wall mounted TV count as an appliance for the purposes of tamper resistance outlet code requirements?
This could be a tricky one, as it depends on what you consider an &quot;appliance&quot;, and how you define &quot;dedicated space&quot;.

National Electrical Code 2014
Chapter 4 Equipment for General Use
Article 406 Receptacles, Cord Connectors, and Attachment Plugs (Caps)
406.12 Tamper Resistant Receptacles.
(A) Dwelling Units. In all areas specified in 210.52, all nonlocking-type 125-volt, 15-and 20-ampere receptacles shall be listed tamper-resistant receptacles.
Exception to (A), (B), and (C): Receptacles in the following locations shall not be required to be tamper-resistant:
(1) Receptacles located more than 1.7 m (5 1⁄2 ft) above the floor.
(3) A single receptacle or a duplex receptacle for two appliances located within dedicated space for each appliance that, in normal use, is not easily moved from one place to another and that is cord-and-plug connected in accordance with 400.7(A)(6), (A)(7), or (A)(8).

Easy peasy if the receptacle is 5 1/2' above the floor.  A bit confusing otherwise.  First you have to decide if a TV meets the NEC definition of an appliance.

Appliance. Utilization equipment, generally other than industrial, that is normally built in standardized sizes or types and is installed or connected as a unit to perform one or more functions such as clothes washing, air conditioning, food mixing, deep frying, and so forth.

Sure, I guess.
Next, you have to determine if the receptacle is located within the dedicated space for the TV. This is made difficult, as NEC doesn't define &quot;dedicated space&quot; well.

110.27(E)(1)(a) Dedicated Electrical Space. The space equal to the width and depth of the equipment and extending from the floor to a height of 1.8 m (6 ft) above the equipment or to the structural ceiling, whichever is lower...
110.27(E)(2)(b) Dedicated Equipment Space. The space equal to the width and depth of the equipment and extending from grade to a height of 1.8 m (6 ft) above the equipment, shall be dedicated to the electrical installation.

Based on these definitions, I'd say the receptacle is likely not within the dedicated space for the appliance.
tl;dr
Unless there's a local ammendment to the code that makes it more clear, I'd say this is a judgement call for the Authority Having Jurisdiction. For the price difference between a TR receptacle and non TR receptacle, I'd probably just install a TR receptacle.
