It would be interesting to see the results. I mean, it would be an expected problem but it is hard to see any difference between "brute force path tracing" alone and brute "force path tracing+PGI" renderings so it is possible that any flicker could be solved by just adjusting some parameter.
There is a varying light intensity under the sofa and book shelf shadows (comparing images side by side reveals the problem).
the variation of light intensity is small but noticeable.
