I think it caught a lot of them, but I don't think it caught them all, at least not enough to load the family up and head 70 miles back into the boonies and have a bearing fail.
The biggest particles were caught, but the main wear causing particles are generally 5-8um and the meshing of gearing and rubbing of gears was filing the pieces so there are an immense amount of small particles. The oil filter I run has the best flow/filtration ratings of any ISB full flow. It's 15um absolute (98.7%) and 7um at 59%. Anyhow oil filters are muti-pass rated, so particles got thru and how many and what damage was done cannot be known until it's out. I also have a 2um bypass, but that only filters 10% of the oil at a time and is there to polish the oil, not prevent big particles from going thru. The oil filter did catch a LOT of materiel, but how many tries did it take? The filters job is to catch normal wear and tear particles, not a rapid influx of small failure materiel. If the filter did it's job then the block will be fine and just new bearings are all that's needed.
The motor ran for at least 45 minutes after the oil pump housing failed, but with the road conditions being noisy it could have been longer. The metal materiel in the filter had a steel and copper tinge to it. It's prudent to tank the motor and replace all the bearings, so really the only added work is the machine/balance work and might as well with it apart. I'll upgrade the pistons/nozzles/cam/springs/pushrods, but otherwise it's just an extensive inspection.
