tiktok换区是否多余?

Recently, when I accessed TikTok using Shadowrocket, I saw the log showing the domain name tiktokv.us. I'm not sure if Shadowrocket can capture packets, and tools like Proxyman also need to be connected to a VPN, so I can't confirm the configuration outside the `_region=` domain name in https://raw.githubusercontent.com/Semporia/TikTok-Unlock/master/Shadowrocket/TiKTok-JP.conf. At the same time, domains such as "byteoversea.com, tik-tokapi.com" are not included in the log. Is this related to the account region in https://www.youtube.com/watch?v=LSjBOZNTcpo&t=1m43s? The pinned comment in https://www.youtube.com/watch?v=3ybR4Whxh04&lc=UgwqE24LEkZJR_96V6N4AaABAg says that under the condition of location services disabled, the region is not restricted. Is that right? I initially registered using a US IP address, so there should be no "location services" https://www.reddit.com/r/Tiktokhelp/comments/16yepq9/comment/mvl8f0u/?context=3&utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button.
