Maybe, partly.
I feel your pain, but it helps!
That's the real answer. Build the perfect room and not try to correct a poor one! However, that's not always (almost never) practical for domestic arrangements, so DSP is the only feasible mitigation strategy. It comes "free" with Roon, unless like me it's the sole reason for subbing to Roon.
I care for a good studio, but not that much for a room that is treated like a dealer selling audio equipment with panels everywhere.
A lot of of audiophiles who come up with their advice and starting to treat walls, start placing whatever they come across behind the rear of the speakers. You often see them on youtube. When not having bidrectional or omnidirectional loudspeakers, that wall does by far the least in measurements. It looks good on camera or interesting to some (look he is a real expert.. ) to have a pair of speakers and something on that spot, but apart from that. There was someone who bolted a diffusing panel behind the rear of his speakers, I don't know what that serves for in that position. He also didn't hear much of a difference.. for obvious reasons
Vinyl on the record player, vinyl on the floor, Pair of curtains, shaggy carpet, seats, an average amount of plants, and all common things that a living has on the wall is more than enough to dampen it under normal conditions. Eventually maybe go for one panel if you really have a big problematic spot.
As an expert in room treatment mentioned. Search for the sweet spot between 'too much reverb' and 'dead as a brick' and you're there. Loudspeakers are meant for living rooms, always have.. always will.
