Yes, but it all kind of depends below the P. It still seems to me it's still largely the panel manufacturer, as much as they try to convince everyone otherwise ('the 5x-70 are similar'). Sure, scanning backlight tech helps a lot, but as a baseline it surely matters where your starting point response time is.
Now, this is theory, not a fact. I've simply noticed a pattern and applying some logic.
Take a baseline of 5ms, which seems to be where AUO often splits their stock (Higher-end Sony/Samsungs vs lower, probably the M versus E, probably all 4k panels at this point...regardless of what vizio's manual or AUO's panel spec list). Not only does 5ms or lower seem to afford them 20/40ms (or lower) of input lag (depending on implementation), but also better motion resolution. Since 5ms or slightly better could allow 200hz (or practically up to 192-216/210hz, if talking frame multiples) with soe, or roughly 400+ lines of motion resolution, from there I imagine it scales motion with the scanning back light. With the 60 inch M, the Sharp panel scales from at least 300 (150hz) to around 1080 (essentially 180hz with 3x scanning backlight) lines with it engaged, but can't complete 400/1200 (200hz), while the input lag (based on a theory of roughly 8x response time) suggests gray-to-gray of around 5.2xms, (where 5.2 is the cutoff for a 'great' input lag), which tbh is really good for a Sharp display, but black to black (for motion) is then probably similar, and still higher and under 192hz (over 5.2ms), or 8x*24fps film.
This could relatively effect performance, and I see this spec (for motion/input lag and scaling) as a key threshold I only really see AUO succeeding in (for as-of-yet reviewed products).
This really doesn't matter for the p, where both should eclipse 1200 regardless (as long as under 6.66ms, which all 55+, at least, surely are) but something to consider on the M, and really for all manufacturer's models when comparing sharp and auo. There are other things of course (like sharp's generally better contrast, but red push on their gamut, where-as auo is seemingly more blue and seemingly tailored toward RGB, ala a computer monitor.) It's just a piece to consider, like everything else.
Also, this can't be verified until we see a 'geek box'-like breakdown between a similar sharp/auo model and compare, but I imagine this theory holds somewhat true, and we could see the 55 and/or 65 M reach 1200 lines of motion resolution without the extra strobing the P does...more likely the 55 than the 65 because of 5/6.5ms ratings (if vizio/auo's ratings are to be believed).
Oddly, according to available panels and their specs, the reverse will be true of the P (where-as the 65 is rated at 5.5, the 55 at 6.5...but odds are both will be below 5 for all intents and purposes). At this point, it becomes purely a curiosity as corresponding to input lag.
