I would delegate this to those with more everyday experience, aka "AVS forums" - they know this stuff inside out,. back to front, upside down etc - this is their bread and butter. The "smart" TV manufacturers are NOTORIOUS for abandoning their shitty products - these sets are NOT their main and/or sole interest, and thus, they have ZERO interest in keeping them patched/supported, just as with the gangantuan array of TRASH Android handsets. They care about repeat sales, not repeat updates for older machines. My 2015 Roku is STILL receiving the latest OS updates, I check it once every 6 months, and the same cannot be said for the JUNK "smart" TVs.

Nope for quite some time it has been impossible to dissociate things as they was..
Audiophile HIFI days -GONE
AV integrated SHITE - GONE
Video standards - GONE
the list goes on
Presently the cost of these "SMART" gizmos boils down 75% to 85% just onto the PANEL.
Those who manufacture the PANELS are making money...
The rest of the stack is IP property piling like nuts
All things converged and blurred to 2 or 3 brands which detain the vertical stack
AMD/ATI NV/ARM and the whole ecosystem around ANDROID TYZEN and smart gizmos made from what once upon a time was open software..
Apple gizmos are not very much different.
Piling the whole stack into silicon will be the next step..
They won't be repairable..
They won't be open in any terms .
Vendors will obsolete that shit at will at insane rate..
We urge need to get rid of these trends...
They are already at pace.
Software can do much more damage into our lives than old style hardware locks
