With the absence of any Oyranos dependencies that would be a question of
standardisation. In Oyranos we have some kind of driver handshake to allow
the device modules all sort of tricks in order to extract and serialise
the calibration state. Many modules need native library access for that.
So we would much need a library interface, and some kind of simplified
module C API for dlopen'ing from other parties. This architecture allows
Oyranos a relative big freedom from upstream project developments.

With SampleICC and IccXML it is instantly available. One needs just some
ICC XML snippets and the drivers colour calibration text to embedd.

Oyranos ICC profile API gives access to the dict data. This is deployed in
ICC Examin. As mentioned SampleICC can do this as well and lcms will
likely follow too.
