This is also true, I still think it depends on the album in question as well. If you take any clean OG pressing pre 1980-ish, I can almost guarantee it sounds amazing. The rub and challenge is finding some of these albums in really good condition, take for instance albums that have come up recently in here like The Nightfly, Brothers in Arms and or something like The Alan Parsons Projects- I Robot, you can, with a little patience, come across clean OGs in the wild for a $10 spot or so and they are beautifully recorded and mastered.
The argument is always is the more modern "audiophile" pressing $xxx.xx, better than the OG when talking about MoFi, AP or any other audiophile repress/remaster, my honest answer, I don't know. Again, using The Nightfly, the One-Step is by far the best sounding this album has ever been in my opinion, digital arguments aside, but is it $450 better (just using Cogs high as the example)? Probably not for most, but for me, and I paid much less than median value for my One-Step, it was. It's been one of my favorite albums since it came out and I really love Fagen/Steely Dan's production value and talent, this album has stayed with me in one format or another since 1982.
It's a hard argument to make when deciding what the definitive anything is, again, there are so many variables involved, but hopefully the comments of like minded people with similar tastes and equipment, can help narrow the search for a lot of us.
