True.

More generally, in a stream in the Ogg file.
Codecs are streams, but so are things like
Ogg Skeleton.  Information about Metadata
has been collected together in the Xiph Wiki
at:
    https://wiki.xiph.org/Metadata

I have never used Theora, but according to the
spec this stream can include VorbisComments.
Details of these are at:
    http://xiph.org/vorbis/doc/v-comment.html

and at:
    https://wiki.xiph.org/VorbisComment

To address your specific questions:
1.  There is no standard field name for color
    space or for an ICC profile; you would
    have to roll your own.
2.  COPYRIGHT is a standard field name.
3.  A timecode could go into a DATE field
    as described at:
