It obviously makes sense to turn room correction on and off and check the difference over the range of seating being used in any given situation. Do no harm, etc.
The run-ins I've had with room correction, with my own cheap hi-fi gear, as well as the and higher end stuff my cool friends have, indicate that room correction can be very handy.
Even the room correction built into the 2018-model EUR 400 Yamaha amp I have at home does more good than harm, with the little Genelec sub and Polk satellites. That is, in a regular residential setting, where everything doesn't happen on the terms of audio reproduction, to put it politely towards other concerned parties.
Similarly, this cottage thing revolves around my synesthetic friend's family owning and keeping up the place in a multi-generational social dance of compromise, which this very stylish friend finds annoying and moderately embarrassing.
There's not exactly the tasteful minimalist decor my friend would prefer, but a type of deliberately shabby, cartoonishly frugal kitsch you'd typically find in Finnish summer homes, where people just want to feel freed of suburban respectability norms. More to the point, my friend's mom wouldn't take kindly to acoustic treatment interfering with her live-laugh-love game.
I on the other hand have done the political hand wringing required to have my living room seating arranged for audio in the small apartment I share with my SO. And the sub is placed behind my couch where there happens to be a sharp, little corner that nicely traps bass resonance elsewhere than the couch, so DSP makes smaller adjustments.
Likewise, my Yamaha amp's room correction saved me that hour-or-so of annoyance of flipping DIP switches back and forth on the bottom of the Genelec sub to manually listen for the correct phase setting, or whatever it's called.
