Update: I did a factory reset of everything and double checked that I was also on the latest firmware --
Before even applying any settings in standard things started to look better! Applied some settings and tweaked them to my liking!
Tried Mandolorian and it was still dark (have come to the conclusion that its the fault of the show) HOWEVER it looked a lot better than it did before with similar settings.
I tried a few different pieces of content from various sources and there is absolutely a difference here!
I will note that I am no longer using the built in apps and I have switched to my 4K Roku for this. I have noticed that the quality provided from the Roku is definitely better than that provided from the built in apps (Could be due to the wifi chip in the x900e but who knows?
I have gotten this TV to a level that I am now pleased with and I think it looks better than it ever has before at this point!
Thank you to everyone that helped out and if you are having similar issues and have never done a factory reset either before or after updates; I would highly recommend it.
TL/DR: Factory reset the tv, picture already looked better -- applied some settings and tweaked and am very happy with the outcome!
