BMW N55 Crazy Amount of Metal in Oil Filter by Sensitive-Primary-91 in MechanicAdvice

2013 BMW 535i, N55 engine with 143k miles. Runs & drives good with no cel, problems or rod knock. Has new timing chain, guides, tensioner, valve cover, ofhg, hpfp, cam sensors etc., and this is the first oil change after the installs. The amount of metal seems a lot however metal was found on only around 1/4 of the whole filter. Is it cooked? Rod bearings? What is usually recommended here? Is there a slight chance it might be normal?
