The moral: If one needs to experience the full power of the bg bots one needs to change the default settings which are configured for the average user. Whatever errors bots occasionally make at their evaluations, they make up by searching deeper.

I agree that changing the default settings helps, but your second statement is wildly optimistic. You got lucky in this one particular position, but I can easily produce many positions where the bots are obviously confused no matter what search depth or move filter or rollout setting you use. The easiest examples concern superbackgames and snake rolling. Put five black checkers on each of the 6pt, 4pt, 2pt of black's home board, and put five white checkers on each of the 5pt, 3pt, and 1pt of black's home board (so it's a "superbackgame"). Now ask for the cube action. Whatever setting you use, you'll get nonsense.

Or try putting 2 white checkers on each of black's 1pt, 2pt, 3pt, 4pt, 5pt, 6pt, and 3 white checkers on black's 7pt. Put two black checkers somewhere else on the board. Now sit back and laugh as you watch the bot try to roll white's prime around the board.
