How do modern 60 Hz TVs handle 24p outside of 2:3 pulldown?

Your question doesn't make much sense to me.

But effectively your TV will only refresh at 50 or 60 cycles per second (hz).

What you plug into it (Blu ray, games consoles) are the technologies which allow 24p playback. This works as you say with a 3:2 pulldown (or 2:3 pulldown) algorithm which splits between -

Odd frames - 2 x 12
Even frames - 3 x 12

Gives total frames = 60

If your TV was only 50hz, that wouldn't work. Because 24p doesn't fit into 50hz, the historical way of getting round this is to speed up the film to 25p. The pitch of the sound will go up, but its only 1 frame per second so not many people notice the difference. It does shorten the movie though by approximately 4 to 6 minutes.
