For a long period of time whenever a poolplayer was on tv all I'd watch was their fundamentals, and yes you can learn to see what they are doing in relative detail. I learned alot about efren's stroke and grip by watching him on tv, mainly by pausing and rewinding the shots where it was visible. I can also see poolplayers compensating, especially on extreme english shots. You can see it pretty well on 1rail follow shots with inside english.
