Color gamut is stable for all sets at 70% of Rec.2020. (Luminance is measured roughly every 1000 hours so there aren't many data points). The other sets do not yet present an obvious trend. The HDR peak brightness (10% window) has been rising on the Live CNN (200 cd/m²) and the FIFA 18 sets, and falling on Football set.

The Live CNN (bright) set shows serious burn-in, especially on a solid 100% magenta screen, but it's also bad on 100% red, 100% yellow, and 50% gray. The test continues, with the Week 36 updates posted on October 4, 2018. The sets are run in a five-hours-on/one-hour off cycle that repeats continuously.
