Yes, there are many different branches to the C.Chinense flavors and aromas. Fatalis/Bhuts/Morougas have somewhat a similar flavor because of the higher heat and thin walls.
I've found that Orange Habaneros tend to have their own flavor, while Caribbean Reds/Fatali Reds have their own general flavor branch.
7-Pots/Bhuts/Scorpions/Morougas/Fatalis tend to be somewhat similar, although depending upon the color, they will be pretty different.
Whites tend to be fruitier, reds are a deeper "musky" flavor, oranges tend to be rich and complex, yellows are also fruity (yet with a hint of muskiness), browns/blacks are usually deep/rich/earthy and with fruity hints reminiscent of passionfruit or other tropical fruits.
Scotch Bonnets, especially yellows, are always their own unique branch of flavor, too.
There is another branch which I have found several peppers fall, generally speaking, which I refer to as the "Cheiro" flavor branch. CGN21500, Biquinho Iracema, Zavory, and Cheiro White Habanero are all ones which I've noticed similarities in flavor. They tend to taste like tropical fruit, but the peppers are very crunchy and thick walled, and also have a similar hint of apple-ish flavor like many ripe red C.Annuums have.
This is my no means exhaustive, but I hope it gives you an idea about how complex the C.Chinense flavor spectrum is!
There is, however, a quality to all of the C.Chinense peppers that distinguishes them from other species emphatically. If I were to try and qualify it, I would say it is a bright-musky-fruity character and very pungent even with non-hots.
Compare that to C.Annuum which is more vegetable-like with rich notes, or C.Baccatum which is more aromatic/perfumy/pineapply, or C.Pubescens with its deep pepper flavor and tomato-like notes, or C.Frutescens with a tendency to have more of a tomato/onion fusion and black peppery notes. In any case, they are all unique and will all have differences to one another, even in the same species. Have fun as you personally discover the richness and diversity of chili peppers, my friend!
