MPEG-2 can also code interlaced video as interlaced video (MPEG-1
cannot). I'm not sure what the percentages are, but not all DVDs are
recorded as 24p, right? Those that are recorded as interlaced MPEG-2
would have to be deinterlaced either by a progressive player or by a
progressive display.

No reason to assume the player has a better deinterlacer.
