If the CBS MOD release does turn out to be the same copies with no additional cleanup done they would still be a tiny bit better than the Timeless release due to less compression. As there would likely be 7 episodes a disc vs. 9 or 10.
Bummer if these were uncut and improved transfers I would have Purchased it as I never bought the Timeless sets due to poor quality. Looks like I still won't be purchasing it.
