Yes, but the ecosystem is far less mature. I managed to dump the contents of my S90F using this repository: https://github.com/chris-ritsen/samsung-tv-root/releases

The root is transient, and Samsung TVs also have Knox security which I presume you really don’t want to trip. Some parts of the file system are protected by SMACK which even root can’t access.

I’m working on reverse engineering the applications that run in that SMACK context to see if there’s any way to gain access.
