Knowing what the settings actually do would help with that.
Color space "Auto" and/or Native" Not what my eyes see, but what is the TV doing?
Found the answer here - https://www.reddit.com/r/PS4/comment...tvs_heres_how/
I've decided to quote it here as well -
PSA: TCL TV's and Possibly All Roku TV's Here's How to Set TV to either RGB Limited or RGB Full
If you want to change what RGB Range the TV uses, you have to use the Expert Picture Settings option in the Roku app on your phone or other android or ioS device. Scroll down in Expert Picture Settings until you see Color Space option. On my TCL 55S405 it Color Space defaults to Native. The options in the drop-down are Native, Auto, and Custom.
The big take away here is that Auto is RGB Limited and Native is RGB Full. If you want the basis for this statement you may read on below and check the links provided.
The Auto setting in the color space drop-down sets the TV to Rec 709 Color Space which is RGB Limited, i.e. Rec 709 is 16 - 235 scale for black @ 16 up to white @ 235 including "blacker than black" below 16 and "whiter than white" above 235.
The Native setting in the color space drop-down sets up 0 - 255, 0 for black and 255 for white which is RGB Full range.
Here's a link from Roku showing how to navigate Expert Picture Settings from the Roku app for any Roku TV; the table showing color space (i.e. RGB Range) is half way down the page:
Here's the link that shows Rec 709 is the de facto standard that most content is mastered in, and equates Rec. 709 to RGB Limited (16 - 235) (Rec. 709 details are about 1/3 down the page):
TL;DR -- Your Roku TV may not default to RGB Limited, might want to access Expert Picture Settings in Roku app with TV on and make sure color space is set to Auto. Auto is Rec 709 color space which is RGB Limited. Alternatively, you might want to set TV's color space to Native which sets TV to RGB Full. This may only work on with TCL S405 series Roku TV, or it work might on all Roku TV's--I don't know.
2nd TL;DR -- main intent of this PSA is if your Roku TV is set to Native color space it might be defaulting to RGB Full and if you have followed the common advice to set the PS4 to RGB Limited because "all TV's are RGB Limited" then you just might have an RGB mismatch going on until you go into Roku app and set color space to Auto (i.e. Rec 709 which is RGB Limited)
