Live TV Buffer Still Only Stored on Client?

I have not used live TV pause much but now I am. I was testing on a fire stick and paused but after about 10 mins it jumped back to live and started playing again.

Reading posts it seems the "live TV Buffer" up to 90 minutes is still stored on the client device? In this case a firestick with not a lot of space.

Then there is posts about Tunder sharing and on M3U streams those are always shared through the server side buffer, so it's a little conflicting to understand.

Honestly I am not sure why clients are not buffering to the server's SSD's with 1TB of space vs on the client stick. There's much more space there next to recordings, so just trying to understand how live TV buffer and/or tuner sharing interact with each other if tuner sharing is forced on or it doesn't matter if enabled or not with customer channels.

On cient devices that don't have a lot of available storage space, you may want to try changing "Original Quality" (under Settings > Playback > Streaming Quality) to Stream, instead of Direct.

Live TV pausing is the reason I add external memory to my main FireTV devices. But it may be smarter to just select record if you know you are going to pause for an extended amount of time. The streaming option as suggested also allows a selected amount of pause buffer stored on the server, but it does cause a little performance hit when starting a stream.

I am going to test with AppleTV 128GB as well just to compare, but yes recording will force it to the DVR. I know plex works that way as soon as liveTV is started it's stored in the plex transcode directory on server, and then new clietns can start from the beginning of that same feed. Just seems more logical to me to store it were the space is (effectively recording by default once pause is pressed)

And just to add on, you can set this globally for all clients:
