I seem to recall Safari doing the right thing for JPEGs when I was experimenting with publishing red-cyan stereograms [1] where an sRGB (255,0,0) becomes something like (187, 16, 17) on a high gamut display because the sRGB is less saturated than the P3 red. It looks right for a normal photo but for the anaglyph that little bit of blue and green leaks through and makes ghosts. Emedding a P3 profile in JPEG solves the problem. You run into the same problem with print and I ended up addressing those by applying the color profile to the R and L images, doing the anaglyph blend, then attaching the native color profile of the printer -- it probably isn't quite right but the colors are always going to be off for an anaglyph anyway and if I go back to that project I'll design a color grade that pushes the scene away from pure-red and pure-cyan-spectrum colors. What gets me is that the image he's publishing is not really a PNG kind of image.
