Prius ATF Change at 30k mi comment

Thanks to suggestions by members of this forum, I purchased and just replace the ATF in my 2011 at 33k miles.
I had to do a double-take when I saw what came out. At first I freaked and maybe thought that I had opened the engine oil drain since what was coming out looked like old motor oil, and not a bright pink fluid. Not sure if the fluid had lost any of its lubrication properties, but no way would it be good to 100k.
I had purchased the fluid and a local garage charged me for labor to drain and replace. I'm very happy I did and now feel confident to wait another 60k miles and replace again at 90k
