I bought a Samsung "dumb" TV, actually a commercial display from B&H. Other than an annoying popup at the bottom for the terms of service confirmation that goes away in 5 seconds, it is completely off-line. I did connect it to web once to update the firmware, and even then it only had a few apps installed but zero ads. I did reset the network settings and the apps went away.
