I wouldn't be surprised if there was indeed a correlation, but an opposite one. TLJ numbers are lower than the previous one and lower than expected, so they had to sell the right to Netflix to get as much money as possible out of it (and pretty early too). They didn't need Netflix' money for TFA apparently. Or since the numbers are bad, the streaming rights are cheaper than TFA, and that's why one is on Netflix and not the other.
Yeah that makes sense to me. They also sold the TV rights to TBS a couple years ago and then regretted it when planning their streaming service.
