No, obfuscation can only help you get around Deep Packet Inspection (DPI), which detects and blocks VPN traffic. Obfuscation should generally be used in restrictive countries or if you want to prevent network admins or ISPs from tracking your VPN traffic.
Obfuscation can’t help you access streaming sites because these platforms don’t use DPI to detect VPN traffic. For streaming sites to be able to do that, you’d have to use their networks to access the internet (you use your ISP’s network to go online).
Instead of detecting VPN traffic, streaming sites detect and block VPN IP addresses. To get around that, you need to use a VPN that refreshes its IP addresses very often — I recommend ExpressVPN because it consistently works with 65+ streaming services, including top sites like Netflix, BBC iPlayer, and Amazon Prime.
