From what i have learned the only proper way to actually correct the room is to change the actually change the room accoustics itself, you don't have to build a full anechoic chamber to get significant benefits there.
The main thing EQ is good for is correcting for flawed speakers and as we have seen often even very expensive speakers have inaccurate frequency response. Buyers are often in denial about this and it seems like the makers of "room correction" software play along by pretending the room was the only problem. People naturally do not want to hear how the speakers they spent 20000$ on aren't very good.
It's very rare for speakers to be within ±1 dB in terms of frequency response, it's very much achievable even without any EQ but then you have to use expensive drivers and audio companies rather spend that on marketing instead for the most part.
I can see very advanced software being beneficial if you have extra channels that is controlled by the software but that would require extra speakers which is more expensive than simply fixing the room (if the speakers are very high end).
