I would NOT change viscosity. And if you did, why 90? Why two steps, lower viscosity? Maybe, maybe think 110.
Anyway, the fluid definitely looks contaminated. Hazarding a guess it had some intrusion (water, dirt, wrong juice) at some point in the past and the simple drain didn't get it out. New fluid just picked it up.
Mixture doesn't bug me as a short, very short flush run. Might actually help as a flush.
Get better SOON. Just thinking about that feels painful!!
