Yes, the LG Netflix app works as well as anything else I've used (and continues to work after opting out of the various agreements for adware and telemetry, for whatever that's worth). In fact, the LG "magic" motion-sensing remote is quite nice for streaming app UI navigation that's often hit-or-miss on platforms that lack a touch interface or pointing device.
With that said, I only connect my TV (which is also my computer display) to Wi-Fi when I'm actively using one of the built-in streaming apps (so infrequently, most recently when the new Expanse episodes dropped, because Amazon, unlike Netflix, doesn't support 4K streaming on PC or Mac).
