Wine experts also can't tell if they're tasting 3 glasses from the same bottle.
I don't mean to say you can't stuff up a batch of wine, but basically everything that made it to the store in the current state of quality control is good enough to not be told apart by anyone.
No. It is possible to select three different wines that even people with excellent palettes can't really differentiate between, and it is possible with some suggestion to make people believe the same wine is different wines. It is also true that some wine "experts" have terrible palettes.
That is not the same piece of information as "wine experts also can't tell if they're tasting 3 glasses from the same bottle".

They literally fed the same judges the same wine in multiple glasses and got different scores.
