Some (maybe even most) of the 1L will be fine. I bought 14 of the 1L plastic bottles this summer and all were fine. Just pour the entire bottle into clear glasses and inspect before using. I then used a funnel to put back in the black plastic bottle.
I posted this in the other thread much earlier, but Toyota/Lexus should have traced the source of the problem upstream, identified the faulty batches, then traced where they were distributed downstream and pulled them. Corporate has known about this problem for some time, since at the latest June '21, as another user saw an email from Lexus corporate at that time, acknowledging the problem and instructing dealers to not use the current part number of fluid.
