Regarding error bars, I don't know of any examples treating objective metrics but there's some discussion of confidence intervals for subjective viewing results in section 4 of doi.org/10.1186/s136... which might be useful. Mathias Wien might have written more about this elsewhere also.

We present a study on the validity of quality assessment in the context of the development of visual media coding schemes. The work is motivated by the need for reliable means for decision-taking in s...
