This is what I found.

I am holding it as it came away from the engine.

Am I seeing this correctly is the shim between the gasket and the O ring, if so it's not in the correct place, shim first then the O ring held in with the cover, and I thought the O ring was always white, last one I got is as well as my spare is white, Kurt is correct as well you need to measure that canister depth to see if you need a gasket or not.

Understood. That’s the gasket which so I’m told is not required along with the shim on post 1990 machines.

It might be an shadowy illusion to my eye...pink looks like a shim. Orange is gasket, blue is o-ring...but you knew that

That is an incredible observation, and if I did not know better then I would have agreed with you that was a shim. However, it must just be how the photo was taken because there honestly was no shim fitted.

I saw the shim too at first but it's an optical illusion, the OP later stated there was no shim and as Rob pointed out, on that model year there shouldn't have been a shim and neither should there have been a gasket which was essentially the cause of the problem.

Some say the whole $2000 O ring thing is over hyped and people fuss over it too much but it seems to me that this is a perfect example where whoever built that bike, didn't know what they were doing when it came to fitting the filter. I don't think it's over hyped if it saves someones engine. Having already done 2000 miles I trust and hope the OP got away with it, no thanks to the bikes builder.

On the black O ring, I'm pretty disgusted with a major UK supplier substituting cheap standard 70 shore O rings for the correct part which is considerably softer. They sold me one and I've never used it and won't buy from them again. No way is a 70 shore O ring going to accept the same amount of compression as the correct item. Next thing we'll hear is someone has stripped the threads in the crankcase trying to get the cover flush. I don't doubt a Black O could be used but only with another level of care in reducing the target amount of compression. Filter replacement is complicated enough without a supplier who should know better making it even worse.
