Haha! Awesome. How exactly did you dial in the gamma?
I'll tell you my settings. ISF dark mode; I have kept OLED light at 90. Contrast at 80; it minimizes ABL. Peak Brightness at High. For 3.2 gamma, I went to white balance, switched to 22 points IRE control, raised the target luminance of 100 IRE to 500, and then adjustment meter to +50. So max luminance becomes 550. Then for each step, I used this formula to calculate the value:
[(Target IRE/100)^Target Gamma}*Max Luminance
So for 550 nits max luminance as we settled above, 95 IRE should have the value: [(95/100)^3.2]*550 which becomes (0.95^3.2)*550 and then 0.84862444357*550 and the final answer is 466.743443966.
When you'll go to 95 IRE in the settings, it'll show the target luminance. Adjust the luminance slider accordingly to hit this number approximately; Increase it if target is below the number, or decrease it if it above it.

So this is kind of like watching only HDR content, but we still aren't running the panel at max luminance, and the headroom is still there, so as long as static elements aren't there, panel should be good for 4-5 years at least even with extensive usage. Even though the OLED light is at 90 with peak luminance at high, because the super high gamma, the overall picture level has been reduced.
