-idenfity always seems to report sRGB colorspace

[noirsoft]

We are writing out custom PNG images (sometimes 8 bit, sometimes 16 bit) and we put in a gAMA/ImageGamma 1.0 chunk, and also make sure that there is no sRGB/Renderingntent header chunk. -identify correctly shows gamma 1.0, but still says "colorspace: sRGB"

ps if it matters: are writing out the PNG images from a different library, we are only using Imagemagick for post-write idenficiation and comparison. I look at the image in a hex editor to see that the sRGB header chunk is not present in the image.
