The following canvas/webgl tests are failing when run on an iOS device because of color mis-matches. I believe they are related: canvas/philip/tests/2d.path.stroke.scale2.html fast/canvas/canvas-currentColor.html fast/canvas/webgl/gl-teximage.html fast/canvas/webgl/match-page-color-space.html fast/canvas/webgl/premultiplyalpha-test.html I will attach diffs for these failures.
