Is my sister behavior tacky?

My sister is married to a family judge and they dont have children. My sister and her husband always spend the holidays in another country by themselves, They never spend the holidays with the family in town. That means they never spend Christmas or New Years Even with my mom, my brother, myself, cousins, aunts, etc. always out. My sister and her husband, they always like to have update things (mobile, fridges, computers) and they enjoy also to eat out and assist to concerts, they have a nice house (they are not rich let me clarify but their house is nice) Two years ago they remodeled their kitchen.

Anyway this year is no exception and again they are out for the holidays. My sister texted me and ask me what and my brother want for Christmas as she is organizing her budget but then the next phrase next to that question is what I find super tacky as i believe that is not a question to ask. Next to the question "What would I want for Christmas she added, let it be not veyr expensive". Really? I mean I would never ask her anything expensive becaue I know she will decline it immediately and Im not that type of person im a frugal anyway, but that is a question you dont ask to another person "What do you want for a gift but dont let it be expensive". She can give me what she wants and that is ok by me. I mean hello!! Maybe she asked because she does not like to spend a lot fo money on her family or anyone becauase she has other expenses but who does not anyway, or maybe because since she is going away she needs enough money for her 2 week trip and she rather spend it on the trip. But even if she went to a trip still you dotn ask that to the other person, maybe she felt that cause im her sister she felt comfty asking me that. Sitll for me that question is tacky like she does not want to spend anything on me beause if it is not cheap she wotn buy it. <im not even telling her what to give me anything wil be fine by me cheap or not cheap.
