The input video used to generate the analysis file(stats) in "save" encode must be the downscaled version of the video used to encode "load", x265 scales only the analysis data, not the input video.
The refinement techniques are to improve the speed of the encode with similar quality when compared to encoding the high-res video without any prior analysis information. Among the different refinement levels, --refine-inter 3 --refine-intra 4 gives the best quality retention.
