As for film scanning, CBS doesn't have film scanning as of 2022.
CBS Digital has rebranded as CBS VFX and will move its production operation to CBS Studios from CBS Television Center.

This is probably why they sold the 2k film scanners.
This guy pretty much said they had those film scanners within two weeks and set up shop.
It's easy to get them when money is allocated, I'm sure if Paramount wants to get film scanners, they can have them set up in two weeks.
I also think Paramount has redundant departments for film scanning.
Iron Mountain recently started installing film scanners into it's storage facilities, and
Strattaca is a similar company to Iron Mountain, Strattaca Salt Mines stores the film negatives.
Also, if the price were 17 million to remaster DS9 from the negative, 100,000 buyers of 7x $85.00 boxsets would make the endeavor profitable.
If it's 3x the amount of money, then it's 68million back, or 51 million in profit.
DS9's fanbase is 3 million, if 80 percent of them wanted the boxsets profit would cross over 1 billion dollars (I seriously doubt the demand is that high.)
Give or take the cost of manufacturing the boxsets.
