Just changed over to my first "real" tracking period as Lumo after upgrading earlier in the spring. No new set of vouchers to be seen upon changing to a new tracking period, as has been speculated here before (in case there were no actual data points yet).
However, flight experiences as Lumo have been very positive so far. On all segments so far I've got some Lumo talk in a subtle fashion, on one LHR flight even had a double Lumo talk by the purser, once after takeoff and another one before landing

One non-FF colleague was enjoying some of the perks and was rather amused at the great level of "customer success" that I was afforded.
