Can the wrong differential fluid cause damage to axel seals

Good day all.

I brought my 2006 Tacoma to my local Toyota dealership and they put the wrong fluid in the differential however I didn't know that at the time. About a week later I notice a grinding noise and brought it back. They said I had blown an axel seal and that the fluid had leaked into the brake drums. They replaced the seal and rear brakes and said that the problem was fixed! The next day it was brought back because the noise was back. At this point they realized they put the wrong fluid in the differential. Can having put the wrong fluid in the differential have contributed to the seal failure?
