I can live with the the display being less crisp (not sure if it is that though since they both have the same PPI and I have compared same-sized text).
It is hard to see in the photos - but the PM has a greener tint when looking at white content and is generally just a little less pleasant with web browsing, Narwhal app, etc. I can't really tell in videos, but definitely in general browsing, iMessage, etc.
I am not sure if it is a Samsung panel lottery situation. But this is my first G9P panel and I do not like it as much as the G9Ns I have had.
Honestly, I compared the G9P on the 17PM to the GVC to on the 16PM that I haven't traded in yet and think I might like the GVC a little more than the G9P.
