Your photo does remind me of Terra Cotta Star. Exotica and Terra Cotta Star are similar, and I wonder if they might be related. I believe that the older Exotica is translucent and has a fairly pale base color with coral markings. Terra Cotta has a darker base color, with coral markings. How long have you had this bulb? Terra Cotta has only been widely available in the last two years. I suspect that Terra Cotta has supplanted Exotica in the trade. I am not an expert on fragrance. Years of antihistamine and decongestant use has destroyed my sense of smell.
