Methods and systems for displays with chromatic correction having differing chromatic ranges

A method for color correcting, comprising:

• performing an initial color correction on source picture content using a non-reference type display having a non-reference color gamut to obtain mastered color corrected picture content for display on non-reference type displays having the non-reference color gamut and to obtain initial color correction data directed to reference type displays having a reference color gamut;
• performing a color gamut mapping using the initial color correction data and the mastered color corrected picture content to modify the mastered color corrected picture content for display on a reference type display having the reference color gamut;
• and
• performing a subsequent color correction using the reference type display having the reference color gamut and the modified mastered color corrected picture content to obtain mastered color corrected picture content for display on the reference type displays having the reference color gamut.

A method for color correcting, comprising:

• performing an initial color correction on source picture content using a reference type display having a reference color gamut to obtain mastered color corrected picture content for display on reference type displays having the reference color gamut;
• performing a subsequent color correction using a non-reference type display having a non-reference color gamut and the mastered color corrected picture content to create a first set of metadata directed to non-reference type displays having the non-reference color gamut;
• determining a second set of metadata defining a color gamut mapping specification from a non-reference type display to the reference type display;
• and
• generating a final set of metadata from the first set of metadata and the second set of metadata, for a subsequent color transform that color transforms the mastered color corrected picture content for display on non-reference type displays for consumer consumption,
• wherein the source picture content is mastered for consumer consumption only for the reference type displays having the reference color gamut.
