The question is if the lack off strong-intra-smoothing is directly related to the defects in this picture, or if it saves that much bitrate elsewere so that bits can be spent on details in areas that are otherwise blury. Eitherway, I can't really find any parts that looks better with it disabled, so it's not like it causes obvious smoothing were it shouldn't.

I would expect SAO to help more as bitrates go down and CRF goes up.

All tests are 2pass VBR, and the question is not regarding SAO but strong intra smoothing. But in terms of SAO, disabling it have never caused any side effects for me outside animation and very low bitrate material. It doesnt effect encoding speed, or increase bitrate @ given CRF level.

As stated, uncompressed (not really true though, its re-compressed to FFV1, so actually lossless not uncompressed).
