If you are only seeing glitter, it is quite likely that the filter caught it all!
DO NOT THINK THAT THIS WILL HAPPEN TO YOU!
One lister wrote how he rebuilt his engine in detail after a failure (don't recall but I believe it was due to IMS failure). He was meticulous in the rebuild, EXCEPT.....he did not replace the oil cooler. On start-up, the engine was ruined in no time from shrapnel left in it . It is easy to check the "looks" to see if it's new.

Bought a Cayman S off the classifieds on here. Engine was just gone through with new bearings and seals by a reputable dealership. It’s been about 350 miles since the rebuild. Today I swapped out the OEM filter for the LN Spin on adapter and a Bosch canister filter. So I pull the OEM and dump it into a pan and find both shimmer and a few bits of glitter. I looked in the filter pleats snd saw a few more specks of glitter. Car runs great. No noise or smoke. Should I be concerned or am I just looking at ‘break in remnants’? After another 500 miles or so I’ll be adding a magnetic drain plug as well. Haven’t reached out to the seller as nobody wants to be hassled after they’ve sold a car.
Thanks in advance for your replies.

I’m looking for an answer to my initial question of should I be concerned. I’m not arguing with anyone. I’m clarifying my situation. I will check if it is magnetic in the morning. That is a good question. It was built by a 28 year veteran Porsche tech that I bought the car from. I was told to change the oil at 500 miles. Not sure if it is break-in specific oil or not. Thanks for your response.

i would think a little metal shavings on a newly built engine is normal during it's break in? drain the oil and check again maybe in another 500-1k miles? but i'm no engine expert. I know that even new cars can have some metal on first change.
edit* looks like 85gold beat me to the punch

Beyond that, your best bet is to change the oil and then see how it does at the next oil change. I don't think a used oil analysis on this sample is going to be able to tell you if the material is leftover crap from the rebuild or if it's fresh wear.

That's about a 20 boat-dollar-plus engine and the rebuild is, to me, suspicious. You have to be worried. Definitely change the oil. Glitter is babbitt material and is not unusual after a rebuild, it's steel and aluminum that are the scary ones. How were you told to break it in?
Why use a spin-on? They are a bugger to cut open and therefore you won't likely do it and it's the best way to take your engine's "temperature" as you just found in the oem filter.
Suspicious because dealers rarely rebuild, they swap. Any damage that destroyed bearings has to have ruined other areas too. Overheat, over rev, low oil from tracking? What did the overrev report say? What exactly was repaired?
Did you get a warranty? What year is it? Does it have an IMS?
Definitely you should be concerned but you won't find your answer on here.

I would advise pulling an oil sample after 1000 miles since you already changed the oil. I would also recommend dropping the sump to inspect for any debris there.
As all they did was change the main and rod bearings and seals, I wouldn't expect there to be any glitter. The only time I have seen non-ferrous glitter in the oil is when the main and rod bearings have been compromised on track cars OR if a freshly rebuild engine is cranked over to try to build oil pressure. Many shops have wiped out new bearings this way.
