In the video below Passage of 7 Starlink satellites including (supposed) "darksat" world renowned astrophotographer Thierry Legault is not impressed by DarkSat's darkness:
SpaceX said they have coated one of the satellites (the "darksat") to make it less reflective...if ti's really the #1130 (alias Starlink U), it's not really convincing!

Question: Have any photometric measurements of DarkSat's darkness been reported? These few-pixel images appear to be saturated so I don't think we can compare the brightness of these unresolved dots in the video.
