I had the same reaction!
I think it's fine you let it go today, OP. Ice cream at a party isn't going to turn your DD into a princess and it's not the battle to pick. I think that you have far more influence over your DD than your mom, and how you choose to parent your DD will eclipse everything else. If she's not spoiled in your household, she'll come to recognize that grandma spoils her but in the context of the grandparent/grandchild relationship, it won't be a big deal. My grandparents let me have candy and sweets - I loved it but it was a special treat at their house, not something I experienced on a regular basis - my mom's rules guided my every day life. I realize that's a very superficial example but the bottom line is that your DD doesn't have the same history with your mom, and none of the baggage because she's being raised in a different household, with you as her mom.
All that being said, if the other grandkids are noticing favoritism and it's blatant, I would take whatever steps you can to decrease the impact or prevent the behavior, if at all possible.
