I would recommend checking also slower movement such as panning and
scrolling text.
Different processing gives different behaviour.

At least when upsampling SD, some of the blurring comes from the image
processing (or the material it self).
Many blurring scenes are still blurred when I freeze the picture with
the Freeze function on my LCD-TV so that is not introduced by slow
response in the panel.

Well, isn't it the other way around? With low ambient light, you need
deeper black level to make it look black instead of grey.
"Black" is very relative to what you compare and the surrounding
brightness.

One effect that can be seen in well lit stores is that certain plasma
screens gives much lighter grey than many LCD-panels because of the
treatment or material of the screen surface. The same can be noticed
with the panels that have a very gloss surface. At certain levels of
ambient light, you see an image of yourself reflecting in this type of
screen especially in the areas that should be dark.

If it is difficult to see details in the dark areas because of too
much ambient light, maybe more overall brightness is needed.
It can also be caused by the "demo settings" that gives too much
contrast (for the screen to handle).

Maybe the amplitude resolution in dark levels varies between models,
but in general, the contrast and brightness settings need to be
adjusted so that "almost black" can be distinguished from the lowest
level of dark,dark grey the panel can create.

With an LCD panel, I think the best results are achieved with some
ambient light left on. The level presented as ambient on "DVE" (is it
20%?) works good. In a dark room the black level will look dark grey.

Same here, adding the (mostly) smooth, blink free and reflection free
presentation.
