I know the theatrical 2.6 gamma encodings are relative, not absolute, but to make things completely consistent, would it be better to say that for a theatrical environment you should use a peakLuminance that is 100 / 48 times the target peak?
That way SDR cinema would use peakLuminance = 48 * 100/48 = 100
Dolby Cinema would use peakLuminance = 108 * 100/48 = 225
and DCI HDR would use peakLuminance = 300 * 100/48 = 625
