If CBS cut the budgets for this project the rest of the seasons could be in line to look much different than season one, regardless of whose producing them.
I'm doubtful this is a case of budget cuts. HTV-Illuminate took the same stock shots from Season 1 and changed them to their 'vision' rather than try to match the look established by CBS. This was artistic choice on their part. Again, I have my suspicions that this comes down to Dan Curry guiding the team to do make things look the way he feels they should look. I know he worked on the show back in the day, but just because it looked blurry and soft in the 90's due to the tech doesn't mean it has to look blurry and soft in HD with matte lines intact.
