My wife likes strawberries. I don't care for them. Professional wine tasters are just people with their own preferences.
> aging a particular bottle actually makes it taste better in a measurable way.
So Bordeaux 2017 is on sale now En Primuer, which means it is still in big casks in the vineyard. Buy it now and your wine merchant will ship it to you in 18 months when it is bottled. The wine experts have all been to Bordeaux and tasted those wines, and I can tell you you need to be an expert....because this young they are very tannic (like sucking a tea bag!). The skill they display in knowing how good a wine will be in a few years when it is ready is pretty impressive. These wines will all taste very tannic in 5 years time, but in 10 years may soften. So no they don't get better with age, it just takes years for them to be ready to drink. I guarantee you could tell the difference between a 2017 claret and a 2009 claret.... because one is ready, one is disgusting. So sorry I think you have missed the point of ageing.
