Yeah in essence the differences between bookies both make the % of difference and risk it, by offering different odds with different provisos. In the end I guess its better to spend your time on real, big, positive projects, rather than trying to find holes in well established systems.

In fact, there is a problem especially with tennis. In tennis, it is quite common that one of the opponents retires due to an injury. Many bookmakers have different rules: some of them make both stakes void in this case, in some of them the player who had withdrawn is considered as the loser if at least one ball was played; some of them evaluate the stake non-void only if some number of sets have been already played.
So in short, you can lose all your money if you bet on both sides and the match is retired. Moreover, the odds between bookmakers with different rules usually differ a little, so when you find an arbitrage, it’s quite probable that the bookmakers you found have different rules.
Sports like football and ice-hockey are less prone to this problem, I think.
