No, when I google'd it, the links went back years.
If TV manufacturing did that, it would actually add costs, not reduce, say they made 1 million for Best Buy, but then stop, redesign it with one or two less HDMI inputs, make 100,000 for Costco, that would actually make the 100,000 unit more expensive.
It is cheaper to make all 1.1 Million at once, then putting a extra K on the sticker and box on the extra 100,000, that were built all at once.
But, until we have a model number or links, we will have to say Jimbo is mistaken.
Also, the size of the TV can affect how many inputs, a lot of under 50" models only came with 2 or 3.
