I want to match a OLED that is locked to 100NIT Gamma 2.6 / P3 DCI (cant change hardware luminance, its a special display) to a cinema projector .

Source signal is DCI/P3 gamma 2.6 .

first I need to pre-match it and then start a visual approach, ive gotten good results building a LUT that take the source and knocks it down to 48 NIT using luminance mapping in a colorspace transform in davinci.

But now I imagine that I need to also match the blackpoint, offsetting the blacklevel of the oled to match my projector, now whats a regular blackpoint of a high end DLP- XEON projector in a reference grading cinema? I just want to ballpark and have the building blocks in place before I go and visually match them.

Is there also a low end saturation loss like LCDs have?

would love to hear approaches for this.

the usecase is remote viewing of a cinema grading session as flawed as that might be as a concept.
