Yup. Get in line. shyts underwhelming as fukk.
what games did you play that have Pro support? I only seen you mention UC4 which ironically is only one of the least substantial upgrades(it was already a looker by itself.) I saw you mention the HDR was meh but then that sounds like a YMMV situation as I've seen plenty of people say the games look super good in HDR while some say it looked washed out or somethhing which makes me think that HDR experiences wildly differ from one TV to another depending on settings/other factors.
Have you tried Ratchet?? ROTR? Infamous? 2k17? BF1? TF2? The Witness(HDR patch)?
Sounds like you bought a Pro with some unrealistic expectations despite months of information/videos showing what we'll get(initially).
A game like FFXV getting a 1080P/60fps mode(in DEC) on the Pro when that isn't even supported on the base mode is substantial imo since on PS4 it's 900~1080P/30fps.
