Is there a situation where 14-bit sRGB isn't enough? There are a lot of weird color matching issues on the web caused by inconsistent application of ICC profil

  An image that is in Adobe RGB, for example.

  Storing HDR images, where the brightest parts are greater than 1.0. That way, when you later edit the image and adjust the levels, new detail comes into view. OpenEXR is the best we have for this now. It uses half-precision 16-bit floating point color components.

  BPG supports CMYK, and to re-render CMYK correctly (on a display, or an inkjet printer) means ICC support is mandatory. Otherwise, there's no point supporting CMYK at all. sRGB is designed for an 8 bit per channel encoding, so while it makes sense to support 10bpc to mitigate quantization effects of higher compression, it makes little sense to support more than 10bpc unless wider gamut spaces are supported. If the intent is for BPG to replace JPEG in-camera renderings, rather than converting existing JPEG and PNG to BPG, then it needs to support spaces other than sRGB. This doesn't require explicitly embedding ICC profiles but the spec needs to, well, specify at least one way of preserving this metadata. Otherwise there's no guidance for encoding or decoding the information, and then it's lost. And at that point it's a huge regression from what we have now, and thus no point in implementing it.
