Much to my surprise I found out that many modern TVs do in fact come with dev mode that allow some sort of screen capture.
Safe to say I turned off all the "allow metrics and market/dev modes" and have been happier since.
EDIT> Incase anyone was wondering I did some more research about my model ( im NOT a TV guy ) and came across this regarding what screen content could technically be passed remotely: "Most probable raw grab: ThinQ/SSAP on the LAN after pairing — ~960×540 JPEG. Live Plus/ACR: most probably sends a fingerprint, not a retrievable raw frame." No idea what it means but thought it might be relevant. Remember Im saying in my case it was a coincidence.
