That's how I took it as well.
I do think Bruce was quite smart in TDK, showing plenty of his wits and smarts. The marked bills in the mob's money. Knocking out Dent and stashing him away safely before Joker and his men came in. Getting the fingerprints of the shattered bullet. Wisely using the daylight hours to still be proactive in stopping crime like going to Thomas Schiff's apartment, and saving Reese's life in Lambo (both of which he achieved with detective work before hand). He even learned to not under estimate the Joker after being badly burned by him, seeing right through the Prewitt building set up as being more than it seemed; "It's not that simple. With the Joker it never is".
