IOS app targeting profile view for iPhones only. I have some background images. email@example.com is ~ 333kb, firstname.lastname@example.org is ~ 1.2mb. When I realized the size of the 3x, I loaded the 2x version into both the 2x and 3x slots in my assets. I run the app on a 5s phone and a Xs Max simulator. I see no difference using the original big 3x image vs the smaller one.
These background images are simple illustrations, not a great deal of detail.
Please help me understand this and is it okay to just run the smaller file in both slots?
