I discovered that if you do /give @s minecraft:item_frame{EntityTag:{Invisible:1,id:item_frame}} on 1.20.4 instead, the item frames will actually be invisible when upgrading to 24w13a but if you do /give @s item_frame{EntityTag:{Invisible:1}} it will not be invisible when upgrading even though "/give @s item_frame{EntityTag:{Invisible:1}}" gets you an invisible item frame on 1.20.4
