I have no screen response time or motion blur issues on mine. When did you buy yours?
This has been discussed extensively in the other long thread on the issue, and it's not been proven that anyone has a 16" screen that is significantly or even any faster than anyone else's. The difference seems to come down to whether you notice or care about it as much as others.
It doesn't show up for me when I play games. Did the ufo test and this is what I got. Bottom ufo is 60 fps.

A single photo of the UFO test is not enough to diagnose anything because there are so many variables in the camera and its settings, but in your case you can clearly see the same motion blur that everyone else is getting. The bottom panel is at
15 FPS (not 60), so of course it's going to show a much better result. At 30 FPS you see a very clear shadow image, and at 60 you see what people might describe as the smearing effect with many UFO shadows and a blurry, indistinct background. In other words, the screen response time would need to be
at least 4 times faster to minimise or eliminate the (observable) problem. Indeed, dedicated or fast gaming monitors can be up to 10 times faster than the 16" MacBook Pro's slow screen; so sorry to burst your bubble on that. I'm not saying the screen isn't good in other ways, but it's not correct to imply that the issue is fixed or that there's a chance you can get a good unit by swapping it out or insisting on a repair.
If you still
really think you've got a fast screen, a better (but still not perfect) test would be to record your screen at a high refresh rate (120 or 240 FPS) with a recent iPhone or camera. Use dark mode, a moderate to high brightness, and a dark or black wallpaper and record slowly dragging a Finder window with white icons or other windows around in a circle. Can you show us that? If you can and it doesn't show very obvious smearing I'd be shocked and I'd insist on getting my unit fixed. But I'm very confident that it will.
PS. The one advantage is: if you're the kind of person that likes the motion blur effect in games (I can't imagine who or why!) you can get it for free without any performance hit since it's built into the screen anyway with no ability to turn it off!

A shame considering how much Apple spruiked the graphics in this laptop.
