In your picture there are no spikes visible that any engineer would single out as a problem. The ONLY thing Samsung will want to see is a very flat curve, not a sampled spiky one, which makes even a sine wave look spikey. Your Zoom I suspect will be just as bad at this. You need a real sweep analyser, with adjustable timebases so you can detect the level of every frequency. Your snag is that if you record silence, you do not get a straight line. Look at what you recorded. Lots of more than 2dB spikes across the entire audio spectrum, but they are NOT there. They're just products of sampling in this way. They tend to be more accurate with very loud sounds, but at low level almost threshold of hearing levels, the actual process of 'hearing' these sounds is not really something cheap kit can do - it's just not designed for it.
The facts are you can hear a tone that others cannot, but blind testing with the item being turned on or off, proves it exists. Unless you can document it, you are wasting time and money. Sell the Samsung and spend your money on funding a replacement. It just won't end happily because you know 100% it is the TV but that is not the problem. Making Samsung swap it will take time, effort and money - and possibly the replacement would have the same issue, and they will think you are a loony! We had this years ago with TV sets. The line timebase transformers would often whistle, driving some customers mad, but in the workshop, nobody could hear it, and "the loony at number 13 is on the phone again" would be commonplace. Get shot of the Samsung and buy something different - it's the only sensible solution. You sadly have sensitive hearing, a TV that annoys you, and no way on earth of convincing a man wearing a wig in court. If you brought the Samsung into Judge Judy's court, would she hear it? That's the only thing that would matter. If she listens, screws her eyes up and then says "Bert, can you hear it?" and he shakes his head, it's the end of the road.
Sorry
