No, the front motor stays at the power limit of the LR with boost, as it has been all along and it doesnt have a hairpin stator either.
See this rough overview I have quickly created in Excel:

The LG Packs have a more shallow voltage curve, which results in more power at the lower SoC end. Their chemistry also allows for more power at colder cell temperature. I dont think the peak power will be higher overall, but there might be more power over the SoC / temperature scale than before.
The current M3P with the Panasonic 3L 82kWh starts to drop in peak power below 75-70% and also if the cells are below 15° (or in that ball park).
If you are based in Nevada (?) then you will not get this LG 5L 79kWh battery pack, but you might get a 2022 Performance with the same peak power limits (+16kW). The US updates are far less certain by the looks of it.
