I'm currently playing in a streamed campaign of Ryuutama, and have played in streamed games in the past. There is definitely a difference compared to my regular, non-streamed games.
I'd say the main difference is one of... pressure? If I show up to a regular game-night with my friends, it's okay if I'm a bit sleepy, or lose track of my dice at some point, or we chatter about our days for a bit while someone looks up a rule, etc. It's okay if I have an "off" day. When I play on stream, I have to be "on". I have to be focused on the game, I have to be engaged 100% the whole time, and might need to keep one eye on chat just in case a question comes up, and so on. I cut down on general chatter and even have a different posture when I know I'm "on camera", as it were.
In terms of the flow of the game itself.... in home-games, it's fine if we spend an entire session in which not very much progress is made (we recently had a session of our 7th Sea campaign where one player talked to a shopkeeper about gardening for half an hour, and another went to a bookstore for 45 minutes) - but in streamed games, there's a greater urgency for forward momentum as far as plot and action are concerned.
I don't know which is the chicken or the egg here, but the more cinematic approach to scenes and playing my character is, for me personally, pretty much the same for both streamed games and home-games. I'll think in cuts and dramatic angles and visual framing, etc., whether I'm on stream or off.

Here is the Youtube playlist of the sessions we've played so far! https://www.youtube.com/playlist?list=PL1Iw-pL6Ns8IolqmmhjJfalSa3uBOCyA6
The campaign is heavily influenced by classic SNES-era JRPGs, leaning into the tropes of that. The first season wraps up in April, and then we're going on a break.
