I can't see any tresholds in these Pioneer scans.

I don't record movies, so I am not even familiar with what a "layer transition" issue looks like during playback.
Vinpower scans would likely reveal such layer transition problems in greater detail, but PERU will also highlight them (there are quite a few Pioneer scans on this forum; some of which are actually worse than the scan of the Panasonic disc I shared above).
In my humble opinion, PERU is better suited for:
1. Determining whether an initial recording is of sufficient quality for archival storage, so that it doesn't need to be checked every single year.
2. Providing clear, distinct gradations for periodic assessments during long-term storage.
My first BD-R and BD-RE discs were recorded back in 2010; according to the scans, they remain in excellent condition today. They were authentic Japanese-made discs; quite expensive at the time; and I still make an effort to source Japanese-made media for my optical backups.
