In Answers, we can create a column selector view that allows us to assign specific formatting to every field being included in the dropdown list. For example, if we have both a % measure and a volume measure in the column selector we can set the format of one to a % and the other to an integer. Additionally, we can use the column selector in Answers to create a date period selectable like: Month, Week, Quarter, etc and assign specific formats to each of these columns like mmm-yy for month and yyyy for year.
In DV, there is no such ability to assign formats for each dropdown selection within a parameter and you're instead forced to assign a single format for all of them. This makes it impossible to use the parameter if you want to toggle between fields with different format like % vs decimal. Likewise, when using the parameter to allow a user to toggle between: Date, Week, Month, Qtr, etc you are stuck with only using a mm/dd/yyyy format for all the dropdown values.
