I definitely don’t perceive Ceylon tea as having some other notes than other black teas. And by looking at the page of that brand I would rather expect it to be bland than something fancy
But it might be that we are just from different parts of the world and our tastes are just different.
Or you were given tea as medicine when you were young
As for searching for the taste, definitely try ordering some loose leafs. Generally in teabags the tea often is of the lowest quality
