It depends how much you like 720 video with stero audio. You might get lucky and get 1080 video. I personally pay for and actively use the 4K Dolby Vision video with surround sound, but that's actively blocked by the streaming services in a browser, even though I can stream it in a browser from my Jellyfin instance while traveling to another country on hotel WiFi without much of a problem.

If you mean standard streaming apps the answer is "sort of". You can run them in a browser with significantly reduced quality, but that's it. All the streaming services now require Widevine certification (Android) or the Apple equivalent and _might_ list in the locked down Roku store. They themselves do not support anything better than minimally OK anywhere else.
