Isn't 256QAM on 2.4GHz a proprietary feature?

I always heard that 802.11ac was 5GHz only, and that on dual-band, stations would stick with 802.11n for 2.4GHz

Interesting. How come all the consumer routers I've used have always required 5ghz to use AC capabilities? Are the rest of the ac features enterprisey? Or have I just not interacted with enough routers to see these?
That's not an accurate statement. "802.11ac" denotes a set of features, and many of them apply to and benefit the 2.4 GHz band. For example 256QAM encoding boosts the max data rate by 20 or 33% on this band for, respectively, 20 and 40 MHz channels.
