No, it's not. All you are doing is repeating the same bad information that other people have written.
T-Mobile and AT&T LTE phones will say 4G LTE when they are true LTE, and if LTE is not available they will only say 4G (or 3G or Edge). So, if I get one speed when the phone says 4G and another when they say LTE, then they are clearly not the same, are they? If they were, why would LTE need the additional frequency that 4G doesn't have?
You might call LTE 4G+ because it's a branch of the same IMT spec, but it's most definitely not the same as 4G.
For 4G, per the IMT spec the peak spectral efficiency is 15bps/Hz for downlink and 6.75bps/Hz for uplink. In practice, that's 100Mbps.
However, for LTE the spectral efficiency is improved to 15bps/Hz up and down. In practice, that's 300Mbps.
