Matter of factly, on OLED, there's no difference between 24fps 1:1 pulldown, 2:2 pulldown, 3:3 pulldown, 4:4 pulldown, and 5:5 pulldown, from a photons-to-eyeballs manner. When the pixel is shown 1/24sec unchanged regardless of pulldown, the the pulldowns are no-operations, image being replaced by an unchanged image, with no visible effect.
Now, if you add BFI to pulldowns, it's no longer sample and hold, you can have visible differences -- 2:2 will have double image, 3:3 will have triple image, etc.
Hate to restate the obvious, but I'll repost it here:
EXPLAINER: Why Does OLED Stutter More At Low Frame Rates? (Fast GtG Pixel Response)
Now understanding that, here's links to software-emulated double image effect that is slowed down to 15Hz. This is the same double-impulsing technique as a hardware double-strobe, except double-impulsing via software-based BFI. And 15Hz is a pretty low frequency that has more obvious flicker/stutter effects.
Some people perceive double-image effect as a form of stutter (or a similar feel such as judder/vibration/etc), because it's vibrating between the two positions to some eyes -- whether it is a pure-doubling or a vibrating-doubling, is simply a function of the specific human's flicker fusion threshold. So to catchall more humans, I intentionally lower the Hz to make the double-image effect stutter more intentionally, as a demonstration, that it can happen. It's much easier to see if it's 15Hz or less, for example:

(View at 240Hz)
or
https://www.testufo.com/blackframes#eas ... =2&pps=960
(View at 120Hz)
or
https://www.testufo.com/blackframes#eas ... =2&pps=960
(View at 60Hz)
So the
double image effect can be human-perceived as stutter to
some but not all eyes.
Given how different humans see differently (And the different flicker fusion thresholds that affects the
stutter-to-blur continuum, aka
www.testufo.com/eyetracking#speed=-1 (stare at the 2nd UFO for 20 seconds) where fast stutter just blends/vibrates so fast it is just blur (like a fast vibrating music string).
On OLED, the stutterfeel of double-image effect is stronger than on LCD, so you need a higher framerate to remove the stutterfeel from the double image effect -- but this varies from human to human what the threshold is. For the same human, the threshold is higher for OLED than for LCD, because of faster GtG, which soften the transitions between frames (and thus the extra blur of slow GtG softens the stutters/judders). But the specific thresholds will vary from human to human.
So yes, it can blur or just blends to non-stuttering double image effect...
The stutter-framerate thresholds varies from human to human...
And yes, some people prefer the double image effect over stutter...
But this does not help people who see double image effect as stutter too.
So, it is best not to visionsplain other people, given "semantics-shemantics".
