That is doubtful. If you listen to a high frequency tone, like 1,000hz, and move your head around, you will notice the tone will get dramatically louder and softer. You might move 1" and the sound nulls, and then another 1" and it sounds extremely loud. It'll be loud in 1 ear, but quiet in the other. This is caused by comb filtering and room interaction.
So in room response is highly location and frequency dependent. The dips and spikes can't be fixed with EQ, because it all changes if you move your head slightly.
I don't believe there is a fix for this. In live sound there are strategies to minimize comb filtering by "de-correlating" left and right channels, usually by using multiple mics on an instrument and mixing those mics together differently on each channel. Dave Rat (youtube channel) talks about stuff like this. It's a little off the beaten path, but I think he has some valuable insights.
