OLED motion has two main challenges:
1. Sample and hold causes eye tracking motion blur, it shares this challenge with LCD. Like LCD this can be mitigated with black frame insertion. But so far most implementations of BFI on OLED have suffered drawbacks like flickering or the requisite of using motion interpolation to avoid flickering. BFI works best if it matches the content frame rate, which makes it great for 120fps sources like PC video games, but some find it flickers at 60fps, and it's useless at 24fps.
2. Near instaneous pixel response of OLED is great for high frame rates but can make the judder inherent to low frame rate 24fps movies more pronounced. This can be mitigated by good video processing which can blur the transition between frames, or by motion interpolation (which has its own flaws).
HDMI 2.1 will have little to nothing to do with improvement on these issues. Besides perhaps, it's compatibility with high frame rate sources.
Most advances will be made in video processors and BFI, and perhaps the nature of OLED panels themselves.
Any sample and hold display will always have to surmount these challenges that impulse displays like plasma and CRT don't suffer.
Edit: it's worth noting that many don't find any issues with the motion of OLED. The sensitivity to these motion issues is widely variable. 99% of the public deal with sample and hold LCD with zero mitigations and have no complaints.
