<p dir="ltr">The math is frequently different.</p>
<p dir="ltr">Screen for example in scene referred models is typically:<br>
A or B <= 1.0 A+B-AB ? max(A,B)</p>
<p dir="ltr">max() is often used in place of display referred 1.0 contexts. IIRC, there are a few HDR tools that use whatever the chosen white point value in scene referred is.</p>
