It does but only to live content not catch-up/on-demand. Technically if you watch, for example, a live football match on Amazon Prime you are due to pay the licence fee. This is of course completely unenforceable even by the already low standards of the licence fee and as live content is a very small % of what the streaming services offer they can't blanket charge it.
Twitch streams don't count afaik as they aren't TV-like content.
