when in my old version it has sar 2:1 - will this matter, my previous files which I play on my LG 4K were stretched across the full width and then I used the 3D button to set it to top and bottom and it looks perfect.

The SAR has been changed in v0.86. It is now 1:1 for all frame packing modes (Full and Half SBS and T&B). It seems that it's the best SAR to use with the vast majority of players. It's the conclusion of a long discussion and many tests (starting with
this post).
Do you have a problem with the new setting? AFAIK, as soon as you switch to 3D mode (or the TV switches automatically to 3D mode), the SAR should be ignored and the aspect ratio should be correct. At least, it's what happens with my Samsung TV.
If your TV does not display the movie correctly, try to change Settings -> Full-SBS/T&B aspect ratio. And if that doesn't work, you can edit the __ENCODE_3D.cmd script and change the --sar option manually.

I will consider that suggestion. But take in mind that the 10 or 12 color bit modes are not compatible with many hardware players and/or graphic cards. But I agree that reducing the banding artefacts is a good thing if it works for you. Banding remains certainly the most noticeable problem of the videos encoded in h264 or h265.
