This colorspace API just seem to be the standard conversion matrix being baked into android, really.

It doesn't help as far as hell mode selection is concerned, nor does it give more control over how surface is rendering, at first sight (unless they added a new hook into mediacodec or surface)

 No, it isn't related to mode selection. I also don't think apps can use it. This is akin to what Amlogic is already doing. I think the API can be used to match the source and destination color spaces and do transforms when necessary. It looks like they are using CIE XYZ transforms which is indeed the best way to do color space transformations.
