Maybe it would be less hassle, but if your room is 'off' you run the risk of damaging your new, expensive speakers as the software sets up correction curves boosting certain frequencies with possible 'phut' or 'blue smoke' consequences.
There is loads of stuff available on the SoS website about acoustic treatment and where it needs to be placed. Also some of the reputable makers/suppliers are happy to offer free advice on what you need and where it needs to be placed.
For example:

I say again, if you're serious about mixing and intending to spend on monitors the sort of money you're contemplating, then acoustic treatment is not really a 'perhaps' - it's a 'must'.
Ah! OK; you've edited your post... you don't need YouTube vids you need proper advice... I have a bit of diffusion, but I still have acoustic treatment panels.
