What exactly does indicate it's a Maxwell Gen 2?
For DDR3, yes. DDR4 however can haz higher capacity Chips
It's possibly LPDDR4, which comes at lower volume and clock rates due to lower voltages (and thus lower power consumption). However, a console like the Switch could need the bandwith from high-speed RAM, at 3200Mhz in a 64bit connection in Dual Channel (which seems to be implemented considering they have each their own connections to the custom Tegra chip) it could reach 51.2 Gigabyte/s. If the connection is broader than 64bit (Xbox ONE connects it's RAM with a 256 connection, so it's doable, just not the standard), Bandwith could be much higher. at the aforementioned 256bit the bandwith would be ober 200GB/s in this particular case, way more than the chip could ever need.
My guess is it's (LP)DDR4-2133, but with a 128bit connection, giving a bandwith of 68GB/s, which should suffice for a console like the Switch.

I doubt they'd use something that expensive, it'd most likely be 1600MHz in dual channel IMO.

Only if it's LPDDR4. If it's not the low power version, DDR4 2133 is basically the base model - and thus the cheapest one
When the Switch was conceived, the RAM prices where still falling and lower than nowadays, so it's possible they choose faster RAM than they would do today. LPDDR4 1600 would be too slow, as I can't see any eDRAM - the console would even choke on the bandwith in handheld mode, let alone console mode. At closer inspection, I can only see 64 lanes, which would give the switch with LPDDR4 1600 only 25.6 GB/s, way too low for graphic intensive applications like games. Even Smartphones have a higher bandwith nowadays, and not only the high-end chips.
