I'm no expert and definitely don't have the most refined palate, but from what I've heard and experienced, comparative tasting is the best way to start to dig into and understand flavor.
For me, sweetness is a big one here. Since coffee isn't as sweet as a lot of other stuff we eat, having other coffees to benchmark against with more or less sweetness will help make it more noticeable.
No disrespect for the despecialized and other awesome work out there but 4k77, 4k80, and 4k83 are 100% the way to go.
