If you grew up in a PAL region, 60Hz flicker is nothing.
PAL CRTs flickered at 50Hz, not 60Hz.
I have absolutely no issue with low refresh rate single strobing.
I can't stand to watch a display which strobes at a rate higher than the framerate though.
Double or triple-strobing gives me a migraine.
PWM-driven displays (plasma) or PWM-driven LEDs (backlights, keyboard/mice LEDs, interior lighting etc.) are even worse.
I get bad migraines after a very short period of exposure.
I can handle single-strobe on a CRT at 24Hz even, but start strobing at anything higher than the source frame rate and I can't watch it.
I'll take sample-and-hold motion blur over a double-strobed image or higher rates.

One possible compromise is: Shaders/Drivers with software-based Black Frame Insertion
If someone has the programmer skillz to do this -- Basically a shader/driver that runs in the backgrounds and automatically adds single-strobe support via software-based black frame insertion (blacking-out every other 120Hz refresh cycle), either as a driver or a shader or a video filter. I think this could provide a universal solution, even at a brightness tradeoff...
Black frame insertion doesn't really work well on LCDs though due to the slow response time.
That's why you really need the display to switch the LED backlight on/off instead.
Works great on CRTs and should work well on OLEDs though.
The other problem with software-based BFI is that you have to be able to run the display at double the refresh rate of your content.
Current OLEDs are only 60Hz. They might be 120Hz next year, but that still means you're limited to 60 FPS with BFI.
I'd really like it if ASUS' new HDR display with 384 LED zones had a backlight scanning option that worked at any rate.
The display is stupidly expensive, but I might actually consider it if they synced the backlight scan to the refresh, and supported refresh rates down to say 48Hz with it. (I wouldn't expect any lower)
ULMB being limited to 85/100/120/144Hz makes it a completely worthless option to me.
Ideally G-Sync with single-strobe BFI would become a thing.
