The 265 uses a new version of the ALEVIII tech, and they squeezed another stop out of it. So it’s close, but not the same as the old 65.
I would take this with grain of salt, I do love ARRI and trust all they say, however.
I personally shot ARRIRAW at least 20 hours of footage in extremely different environments with old Alexa and graded in Log C4, image is lot cleaner in shadows I can easily see extra 1/2 stop just by debayering Log C3 to LogC4 as that container allows for more info to be stored.
They probably did some enhancement in order to cool that sensor to fit such a small body but for the physics of the sensor, I am not sure, neither ARRI has clarified exactly what they did other then making LogC4 native format.
