I would not take the lack of a logo as signs of a possible contract negotiation. A little research shows the following...
KIMT is owned by Heartland Media.
According to
this article in 2016, WTVA (another Heartland owned property) had a contract dispute with Dish "four years earlier".
2016 - 4 = 2012.
Assuming the contracts are three years (I believe that's the standard), if they came to an agreement in 2012, they then did renewals in 2015 & 2018.
If the contracts were four years, renewals would be done in 2016 & 2020.
If the contracts were two years, renewals would be done in 2014, 2016, & 2018.
My guess is KIMT is probably good for another 2-3 years.
