So, I found something interesting in regards to image quality that folks who have had the P1 for awhile may be experiencing.
Turns out, even a medium amount of dust on the lens reduces contrast significantly.
I noticed over time that I was becoming less and less happy with the contrast provided by the P1. I thought I was going crazy, but I felt like it was somehow getting worse. I started noticing that whenever there were bright scenes, the black floor rose significantly, and dark areas had a bright halo around them, killing contrast. I also noticed some minor streak lines on my screen, which I thought my screen was developing waves.
Well, my wife and I, while quarantined, did a bunch of deep cleaning of our living room yesterday. I normally never touch a projector lens, but my wife didn't know that, and dusted the lens/projector without me looking. When we fired it up that night, I noticed a massive improvement to contrast and color accuracy and that those screen waves were gone. When I looked at the projector and saw it was super clean, I realized that dust must really be impacting UST projectors because the lens compartment essentially is a dust bin. Traditional long-throw projectors, being perpendicular to the ground, don't seem to exhibit this as the lens doesn't really accumulate that much dust. But USTs, on the floor, and essentially having a valley for the lens compartment, is a perfect storm for having dust affect image quality.
To dust the lens, my wife just used one of those static dust fluffy things.
tl;dr, dust your P1 occasionally.
