To my knowledge, can't compare priv to K1 in that aspect as processor also greatly affects battery performance.
To do this really accurately would be to swap out the 808 for a 625 in the priv or vice versa in the K1 and use same backgrounds and see which lasts longer
Multiple references, but I can't recall them. But from what I gather, you are correct that AMOLED uses less energy than an LCD; the caveat is that this is true when there are lots of black. Measuring AMOLED energy consumption is not so simple as it's dynamic, whereas LCD is constant. Where LCDs have the upper hand is when displaying lots of text on a white background.
The other knock on AMOLEDs that the blue LED wears/burns out quickly relative to the yellow and red LEDs. This phenomenon manifests itself as a drift towards a "greenish" hue over time which the user often does not notice. But I can definitely see and notice this on my 2-year old Priv compared to my Keyone.
This was particularly true and a big issue with AMOLEDS from 3-5 years back. Power efficiency and brightness/wear have improved since then. But it's still an issue.
