The thing is several people like me have noticed that as of the Engine Update there have been some changes to Servants´ art and animations that were not publicly announced (I´m not talking about Nightingale or Arjuna here.)
One example is Mordred, whose eye color was changed and her color palette looks more crisp.
Compare before update:
I´ve been told that there are other changes, like when using Okitan or Kiara´s animations but since I have neither I can´t check that.
So, what other changes have you found in your Servants? And are you happy with these modifications?
