The screenshot posted is NOT a representation of the old "animated water" effect. Don't confuse different water textures on different maps or different tile updates for the animated water effect.
Animated water was removed in 2.10. I can't find too many screenshots of it on the forums (most of them are very old, and the images get taken down over the years). I did find this:

From 20k the water looked okay, but below that it started looking bad... then sad... then "smurfy" and it screwed your FPS and your depth perception horribly because there were no real waves, just light highlights.
