Using a P3 document, with the Canvas set to P3.
Make an artboard with P3 color, export as PNG and untick the ‘Save for Web’. Observe that the colors match those in Sketch
Now export as PNG and tick ‘Save For Web’ and notice that the color is desaturated (expected)
Now export as WebP and you are unable to choose any option keep the color profile; resultant file will appear desaturated as color profile has been lost.
Is there any way to export to WebP and retain the P3 color profile?
