Try doing some research on the placebo effect. It actually makes things taste different or more effective if you think it will work / taste delicious. Really interesting.

Probably I just hate to admit that size dictates mostly what I grow. However I did watch a person who thought he had a palate capable of picking out diffs in water qualities. This was some daytime TV show. They blindfolded him and he sampled some spring waters and some municipal elixirs. He picked city water of Chicago....lol.

Heh. A funny thing to know about spring waters is that they are generally not even regulated when going over-state. That murky brown water? It is magical spring of ireland water!

I can definitely taste the difference between an RRR tomato and a beefsteak. One has much more gel and seeds than the other.

And between a red tomato and a yellow or orange tomato, of course I can tell the difference blindfolded. Now between a red and a pink, maybe not. But between a red and a purple, yes also.

I'm sure I could tell differences in flavors/brix/tart apart ,I've become quite the tomato cork sniffer over time and document them each season.
I make notes of growing conditions ,taste test varieties side by side...ect.

but to be honest If I was blindfolded and someone asked me to name that tomato... I seriously doubt I could.
the closest I could get might be .."that tomato has a potato-leaf Brandywine hint to it" or "this tomato has a zippy green zebra flavor" ...lol

and to be honest.... they change season after season anyway.
