>>So is most of the brightness probably attributed to what we can see in the FR graph? (Aka the 3-6KHz peak and the tweeter peak at around 18-19KHz?)

I think it's just the 3-6 KHz peak. AFAIK the tweeter peak would be countered by the off-axis rolloff at high frequencies. I expect the tweeter peak would only be noticeable if you were sitting directly on axis AND very close to the speakers, which is geometrically difficult unless you put them close together and toe them in sharply.
