An SD broadcast means that the resolution of 576i has to be upscaled to 2160p, and the result is going to be poor on a 75" TV. If you watch a lot of SD your TV is too big, and a smaller (e.g. 50" or 55") will be better.
To add to this you have to bear in mind that the broadcast stream Sky is using is fixed bandwidth. Sky is only using one satellite SD channel to broadcast however many streams they are providing. The maximum they can get away with is 6. So when 6 games are being broadcast the streams are at the lowest quality (bandwidth). If only 4 games are broadcast you should see a noticeable improvement, & 2 games considerably more so.
