I am hoping you folks can offer some insight into this. It isn't a problem but more of a situation. I own multiple Roku devices and one Roku-enabled TV. Two of the Roku devices I own are labeled "Premiere". I bought the first one two years ago to go with a 55 inch 4K TV. That tv is not HDR capable so the original Premiere model was a good fit as it didn't do HDR, only 4K.
Fast forward to more recents events.....
I bought a 65 inch 4k TV this past November. Same manufacturer and not HDR-compatible either according to manufacturer listed specs (8 bit + FRC panel). I moved the 55 inch inch to the basement room and put the 65 inch in the living room. I hooked the original Premiere to the 65.
This past week I ordered and received a new Roku Premiere which appears, physically, to be the same size/shape as the Express+ models I also own. The original Premiere was more of a box shape similar to the current Ultra. The new Premiere is listed as offering HDR. I did not buy it because of that feature but rather because it was on sale and I wanted another 4K Roku device for the 55 inch 4K tv in the basement.
Upon installing it on the 55 inch I ran some TCL Youtube 4K/HDR videos on it to see how it performed and I was shocked by the increase in color saturation, apparent brightness and dark levels. I wanted to make sure I wasn't imagining a difference so I went upstairs and played the same video content on the 65 inch with the original Premiere. The image didn't have the pop of the 55 inch with the new Premiere installed.
So I swapped devices and put the new Premiere up on the 65 inch and, wow, the image is stunning.
My question is pretty simple. What gives? With only an 8 bit + FRC panel why am I noticing such an increase in "HDR performance"? I have attached two pics of some of two of the HDR videos I was watching. I know they aren't a true representation for a variety of reasons but wanted to share them regardless.
