"Display P3" means nothing if I can't easily find color space parameters like with "DCI P3 D65". You are trying hard to invent a wheel again with those "friendly commercial names" (apples's Display P3). x265 documentation also uses "P3 D65" name.

--master-display <string>
SMPTE ST 2086 mastering display color volume SEI info, specified as a string which is parsed when the stream header SEI are emitted. The string format is “G(%hu,%hu)B(%hu,%hu)R(%hu,%hu)WP(%hu,%hu)L(%u,%u)” where %hu are unsigned 16bit integers and %u are unsigned 32bit integers. The SEI includes X,Y display primaries for RGB channels and white point (WP) in units of 0.00002 and max,min luminance (L) values in units of 0.0001 candela per meter square. Applicable for HDR content.
Example for a P3D65 1000-nits monitor, where G(x=0.265, y=0.690), B(x=0.150, y=0.060), R(x=0.680, y=0.320), WP(x=0.3127, y=0.3290), L(max=1000, min=0.0001):
G(13250,34500)B(7500,3000)R(34000,16000)WP(15635,16450)L(10000000,1)
Note that this string value will need to be escaped or quoted to protect against shell expansion on many platforms. No default.
