I finally made the move from my 11 to OLED with my 15 Pro Max, and man am I disappointed with the screen. Apparently I’m sensitive to PWM flicker, and at lower brightness it’s very distracting and tiring on my eyes. I don’t know if this is an OLED limitation, or just this particular kind of panel, but it’s not something I’ve noticed with LED displays.

OLED has always felt like a stopgap on the way to other tech like micro LED, which hopefully doesn’t have the same kinds of drawbacks like burn in and PWM flicker.

PWM dimming is only necessary if you value color accuracy. Chinese OEMs tend to provide a choice to use DC dimming, but I do not think Apple will ever accept the burden of adding another list item to their settings pages.

Most people only notice flicker during saccades. A larger proportion of people will notice scrolling purple/blue smear, that manifests itself at extremely low source current, when you have really dark shades of grey on a dimmed screen in low brightness environments.

As an aside, burn-in and mura seem to be solved problem these days, due to display driver ICs constantly characterizing the I-V curve of individual subpixels and applying compensation using aging models. Variabilities introduced during manufacturing are also optically captured for compensation.

Additionally, there exists compensation circuits within the TFT plane for fine-adjustement of uniformity for each subpixel.

MicroLEDs are not magically immune to the issues affecting OLED. https://www.oled-info.com/measuring-and-correcting-microled-...

That's what the Accessibility Subsettings page is for

Does this page typically include arcane electrical engineering jargon? Perhaps it could be tied to the truetone toggle?

In what alternate reality would I want to turn my screen orange just to not have it flicker annoyingly at non-full brightness levels?

I had 11 and then moved to 13 pro and felt the same. But your eyes will adjust without damage or discomfort. Its just a matter of time.

ironically a lot of chinese brands do have a setting to diminish this oled problem
