LPV downgrade to LNAV

[PT20J]

Solar activity generally is the cause of this. A possible downgrade is shown on the GTN navigators by LPV being displayed in yellow instead of green. I always wondered if the color indication would be carried over to the G3X HSI. A couple of days ago, I found out: it doesn't -- you have to check the annunciation on the GTN to be alerted to a possible downgrade. 

As I was being vectored for the KPAE RNAV Y 16R approach, the GTN switched from TERM to LPV, but the LPV annunciation was yellow, so I reviewed the LNAV minimums in case of a downgrade. As I intercepted the final approach course, the LPV annunciation on the GTN changed to green and the GP scale appeared on the G3X. But, just outside the FAF, the GTN switched to a green LNAV annunciation and the G3X GP scale was removed. The G3X showed the correct annunciation (LPV, LNAV) but it was always magenta.
