My 2021 Challenger Redeye came with the 899 factory installed.
My 2021 Trackhawk came with the 041 factory installed.
I'm pretty sure it's whatever filter they have at the moment.

The black filters, which are the only ones available to us here in Canada, are not a lower grade filter and are no different internally from the white ones except that they are black and do not have SRT on them. The white ones with SRT on them are appear to be only sold in the US and are not even available to us here through Mopar Parts. I did get some of the white ones from the US when a friend of mine was in the US and cut one of each of to do a comparison and found no differences between them.

This is interesting, I have cut them apart as well.
My findings were basically the same as Steve White Motors.
The 041 filter is just a better filter.
