'PAL speed up' is only applicable to native 24 fps film productions, notably cinema movies
And dramas and sitcoms shot on film, or the digital equivalent, which still uses 24fps - such as
Frasier, Friends, Big Bang Theory...
They're shot at 24fps, then telecined to 60 interlaced fields with 3:2 pulldown.
What does look awful is 24 fps converted to 30 fps video by 3:2 pulldown, and
then standards converted to '25'.
If it's done on the assumption that the original was native 30fps, yes, but usually it's just inverse-telecined back to the original frames and sped up to 25fps.
certainly is, because you can hear the difference in the theme tune and the voices when you get it from... uh... elsewhere.
