That's correct. Player level only affects the Level Bonus at the end of the game. But going from level 300 to 500 only goes up 2% from from 26% to 28%. I think people tend to like leveling moreso for the Rubies it gives you, rather than the increase in Bonus points. Japan was capped at 300 for quite a while, as well.
