Actuallyyyyy-
When 5G does become ubiquitous years from now, only very small areas will be able to reap the benefits of super fast millimeter wave connections. Most of us will be using the slower sub-mm 5G spectrum which isn't much faster (and likely not any faster) than a good (4G) LTE connection.
So while the 5G-E icon on a smartphone might seem misleading, in a sense it IS 5G (sub mm 5G) because when sub mm 5G does roll out - it won't be any faster than 5G-E.
