Exactly the same statement is in the Pearl spec sheet. All the known screen sizes (5", 6", 7", 8.1", and 9.7") for Pearl are 200 ppi or less, with only the 5" actually at 200 ppi. Also, the spec sheet says DPI (dots per inch) not PPI (pixels per inch), and 200 DPI is 100 PPI for Triton.

A 200 ppi 9.7" greyscale screen would be 1600 x 1200, which sounds like a significant improvement in resolution. LG demonstrated a mixed grey/color screen with 1200x1200 on top of 200 x 600 color (Nook-like, but with one combined screen), see Color Comes to E Ink, LG Electronic-paper Displays. This sounds like a variant of E Ink Triton, but I guess LG could be doing the color overlay themselves.
