Canvas 15 was originally announced on 2018/08/06 as being 829x1500 pixels, leading to many to claim areas based on a pure rectangle of these dimensions.
However, on 2018/08/10, more details were released: "915,459 pixels, all straight edges, all right angles, it's mostly rectangular". Given that 829x1500 pixels yields 1,243,500 pixels, this means that the canvas is likely to be a shape with coordinates on which pixels cannot be placed, like the donut shape of Canvas 4, or the fox shape of Canvas 8.
At its launch it was revealed the the canvas depicted a smartphone in portrait orientation, with its bezels and UI elements not available for placing, forcing all art to effectively be built on its screen as part of a painting interface - the first canvas to have that mechanic (previous canvases relied on unplaceable pixels being transparent).

Final state
Untouched pixels
Pixels that were never placed on (also referred to as virgin pixels), depicted in white. Pixels that could not be placed upon are depicted in a deep maroon color.
Pixel age
Age of pixels as a brightness map. Darker pixels were placed longer ago.
Heat map
Depicting activity on the canvas as a heat map - the brighter a pixel's color, the more often it was placed on.
