My LG C2 OLED is great. I never connected to the internet. I have never seen an advertisement or pop-up or anything. For all intents and purposes, it is a dumb TV more like a computer monitor. I do not use any of the built-in applications, just literal HDMI1 (appletv) and HDMI3 (gaming pc). I adore it as a TV and would buy one again in a heartbeat. Not cheap though.
