Built-in sRGB web-safe + LCMS2 produces unnaturally bright areas
Compare http://tech.kovacs-telekes.org/files/dt2-rc3-rendering/DSC_9526-nolcms2-sRGBwebSafe-perceptual.jpg and http://tech.kovacs-telekes.org/files/dt2-rc3-rendering/DSC_9526-withlcms2-sRGBwebSafe-perceptual.jpg
The tip of the pine twigs overhead, the blue area on the neck of the T-shirt of the 2nd-from-the-left girl, the coat of the 3rd-from-the-left girl appear too bright.
Exporting with the same settings but using e.g. sRGB_IEC61966-2-1_black_scaled.icc from http://www.color.org/srgbprofiles.xalter causes no such artefacts, the result is visually close to DSC_9526-nolcms2-sRGBwebSafe-perceptual.jpg no matter whether LCMS2 is turned on or off.

If the question is addressed to me - I have no idea. All I saw is the results of the exports, sRGB web-safe and the downloaded profile mentioned in the text, with/without LCMS2, with perceptual and relative rendering. Only the srgb websafe + LCMS2 exports showed this weird artefact.
