I did a little research, and yes glutinous rice has zero amylose content. This is due to a mutation in the gene that would normally produce amylose and thus rendering amylose production to nil.

"It has been shown that waxy rice cultivars contain a lethal mutation in the waxy gene responsible for the synthesis of long chains of amylose, resulting in a null waxy allele. Hence, no amylose is expected in waxy rice." [Glutinous rice is sometimes referred to as 'waxy rice' due to its colour]

"Koshihikari and Jasmine rice, both highly priced for their unique sensory properties, have the same low amylose content (about 17%).."
.."Amylopectin, which makes up a larger portion of rice starch, is also known to form a colored complex with iodine. The amylopectin-iodine complex may contribute to absorbance readings at certain wavelengths and therefore can be a major source of error when it is not accounted for in the calibration equation. Although the amylose-iodine complex forms an intense blue and stable color that has maximum absorptivity at around 620 nm, the amylopectin-iodine complex is reddish brown in color, has lower absorptivity at higher wavelengths, may fade with time, and is reported to be unstable at higher pH."
