I’ve seen the motion processing on a Sony OLED with problem material. Sadly it’s the same and there, otherwise I would have bought one.
Its an OLED issue, albeit I think slightly less worse on Sony and Panasonic
The fast response time could be slowed with hardware in the future. Maybe they'll do it that way for the best of both worlds.
When I compared LG with Sony at the store when I was buying, for motion I saw an obvious difference. I always considered myself sensitive to motion problems, and I really don't see a problem with anime on my TV.
If you put something on a usb stick and took it to a store, you could see again the difference, maybe it's bigger than you remember. Doesn't hurt to look again, you can only benefit
