I've said it over and over, that C41 will yield far inferior results at low temps. This is a diffusion issue, where chemicals give a kick start to the top layer before the solutions even reach the bottom layer. So, you have low contrast, muddy pictures that will give a pastel result. That is what I see here.
There are two possible issues. A prewet is always indicated for C41 to prevent pinholes and streaks. If the streaks persist, then a stop bath is indicated as well. And, a Jobo without a lift is one of the worst offenders for this type of problem.
