15% loss on a 50W load? That's 7.5W. Watching TV for an hour is a little over 1/2 an amp hour.
At what point is it cheaper and easier to add a couple of extra 6Vs than chase efficiency gains of 1/2 amp hour per day or something?

First off, see how the TV warranty or the warranty on anything you buy works out if you cut off the power cord and adapt to twelve volts. Most people are not comfortable with how TV's or appliances work electrically to start cutting them up.
Second, the additional cost for a 12v TV, versus a 110v TV, is probably enough to buy one or two additional batteries for your RV. If you pay attention and REALLY understand how inverters work, then you size them to the job and have minimal loss.
Many years ago, we were forced to run 12v TV's and appliances in our RV's and the selection was slim and usually a pretty poorly made product. Why would I want to go back now and buy a 12v TV with few options, poor quality and high prices.
For me, I'll stick with my generator and large battery bank giving me the ability to choose from any TV or appliance brand, saving me money while giving me the opportunity to select a quality product.

What happened to the OP? Haven't heard any rebuttal. Out buying some more batteries?

24 inch Insignia at Best Buy is 12 volts and $150.00 CAD (dirt cheap in US $)

Off hand because many years ago the TV used tubes that requires higher than line voltage to run well. Today's TV runs on around 12 VDC internally. Parts of it are at significantly lower voltages.
The trick is not to look for a 12 V TV. Instead look for one with a separate brick type power supply that puts out 12 VDC. Most of those don't advertise that as it is not considered important to the consumer.

Not a TV watcher but my darling and I full time and some days we watch a movie at night. I use the inverter to power. I would prefer a 12v tv like originally came in my trailer. I believe the 12v would be easier since I always have to find and dig out the inverter. Move stuff out of the way and set it up. The problem is that I like a smart tv with Netflix and other video sites loaded on to tv. I haven't been able to find the 12v smart tv. It doesn't even have to be the highest quality resolution since I can't tell a regular cd between a blu ray with my eyes.
I believe enough of us just don't mind enough to worry about how the tv draws power. My dad drives across town to get gas for a few cents cheaper, he doesn't mind that he is only breaking even after subtracting the two gallons to get there. He says he just likes the drive and the away time from mom, lol.

The Insignia proves my point, a 22" TV screen, smaller than most desktop monitors and it is only 720p. It's a piece of junk and too small to watch unless it's in your lap.

That's exactly what my 42" Samsung is/was. Power brick says 12VDC 2.1 output.
