the selection of SDR gamma curves on the Sony projectors is very modest just around the Gamma 2.2. In addition, sometimes the Sonys have to fight with a light Gammadrift.
Since not everyone wants to do manual gamma curves with Projector Calibration Pro or the ImageDirector, I'll just make some curves available, which might help in some cases.
The "Custom SDR Forums Edition" includes 6 new gamma presets and complements the standard gamma curves (1.8 / 2.0 / 2.1 / 2.2 / 2.4 / 2.6) of Sony projectors to case by case to choose a better fitting gamma curve. Especially in connection with a slight gamma drift, it may be useful to use a modified gamma curve. In this case, it makes sense to measure the grayscale before using a correction curve.
But even without Gammadrift it may be that, for example, gamma 2.30 likes better than 2.20 or 2.40.
The package contains the following gamma curves, each in the file format for the Sony ImageDirector:
SDR Gamma 2.25
SDR Gamma 2.30
SDR Gamma 2.35
SDR Gamma 2.45
SDR Gamma 2.50
SDR Gamma 2.55
The curves were calculated with an application by me to create gamma curves in 10-bit resolution.

Maybe one or the other can use something like that.
