As bad as some are in the telecom industry, they don't hold a candle to those in the content industry.

Wifi location depends on a bunch of problematic things. First, your SSID needs to get collected and put in a database 
somewhere. That itself is a crap shoot. Next, you can stop google (and some other wifi databases) from collecting the 
data by putting _nomap at the end of your SSID. Lastly, not everyone has wifi or iOS or GPS or whatever location method 
you can think of. BTW, my apple TV is on a wired Ethernet, not wifi. 

Point is, for whatever location technology you want to use be it IP, GPS, WiFi location, sextant…..they can be 
inaccurate and they can be faked and there are privacy concerns with all of them. What the content producers need to 
figure out is that regionalization DOES NOT WORK ANYMORE! The original point was that they could have different release 
dates in different areas at different prices and availability. They are going to have to get over it because they will 
lose the technological arms race. 

There is no reason you could not beat all of the location systems with a simple proxy. A proxy makes a Netflix 
connection from an allowed IP, location or whatever and then builds a new video/audio stream out the back end to the 
client anywhere in the world. Simple to implement and damn near impossible to beat. Ever hear of Slingbox?

Apple TVs get their location indoors using the same method they use for other iOS devices when indoors - wifi ssid/Mac 
scanning. 

Non-iOS devices are often capable of this as well. 

(As someone that spends >67% of his time underground and whose Apple TV requests my location from my underground 
bedroom and is very accurate)

Their app could request your devices location. Problem is a lot of devices (like TVs, Apple TVs, most DVD player, i.e. 
device with built in Netflix) don't know where they are and it cannot easily be added (indoor GPS is still 
difficult/expensive) and even if they could should they be believed. I think the bigger issue is whether any kind of 
regional controls are enforceable or effective any more.

Come now, content providers really just care that they have access to regional controls more so than their ability to 
blanket-deny access (ok, minus the MLB who are just insane). 

And part of those regional controls deal with the accuracy of the location information. 

If their app can request my device's precise location, it doesn't need to infer my location from my IP any more. 

As a matter of fact, it's only detrimental to them for it to do so, because of the lack of accuracy from geo databases 
and the various reasons that people use VPNs nowadays (i.e. for some devices that you can't even turn VPN connections 
off for - OR in the case of IPv6, when you can't reach a segment of the Internet without it).
