They have literally done this exact double blind test many times and shown that for the majority of people, this simply isn't true. And for the ones who can tell a slight difference, it is only on the first drink, if taken neat, when their taste buds are sharpest, and if they're comparing a top shelf to the absolute lowest of the low quality. After one vodka, or if the vodka is mixed with anything at all, or if it's served cold, or if you're comparing to more middling brands...the results are the same as it would be with random guessing. I've drunk about 9 million gallons of vodka in my life, and I would absolutely agree. Get yourself a $15 bottle of vodka. It's just as good and you'll save a lot of money. I'm telling you with certainty that I could I could tell the difference on my 1st, 3rd, or 18th drink. While I'm eating an italian beef. Then you have the sharpest, most well-refined palate on earth. And that may be so, I don't know you at all. I'm just saying, if we were making an actual bet and all I had to go on were your claims vs. the pile of scientific evidence to the contrary, I think the smart money would be on you not being able to tell them apart.
