Why would topaz not leave a streak on an unglazed porcelain plate?

Topaz will leave a streak, it is just that the streak is white and will therefore not be apparent against the white background of the standard streak plate.
ALSO
Topaz is harder than unglazed porcelain (the streak plate), and therefore normally leaves a scratch rather than a streak.

∙ 13y agoTopaz's streak may either be colorless or white. Other than that, no, topaz really does not have a streak.

What is a streak of a mineral?
The streak of a mineral refers to the color left on a streak plate after rubbing a mineral across its surface. A streak plate can be as simple as the unglazed side of a porcelain tile. The streak is the mineral in a powdered form from abrasion with the hard, slightly textured surface of the unglazed porcelain streak plate. The streak color may differ from the color observed in a specimen. Coloration of mineral specimens is sometimes due to impurities. In a powdered form, the impurities are not abundant enough to cause coloration in the streak, thus revealing the true color of the mineral. The streak is used as an aid in the identification of a mineral.a streak mark on a flat surface
