I don't see a test for 2D image like how Jdaviz would store it. We have a 2D array under one component. Here, you store each dimension as a separate component. I don't think it is equivalent?
Since we do not use histogram viewer directly in Jdaviz, I am trying to emulate this calculation directly over at spacetelescope/jdaviz#2763 but without success. There must be some subtlety I am missing. Are you able to have a look over there and tell me if I went down the wrong rabbit hole?
Cami has a 8GB test image if you need one, if she is willing to share with you.

This is to provide a long-term solution for issues such as spacetelescope/jdaviz#2735 where a histogram doesn't have to be exact.
