Roku having problems determining video type

I just bought a new OLED 4K TV: Samsung QN65S90DAF.  Says it's 4K OLED HDR+

Roku is setting the display to 1080P HRD10+.

When I look at 4K Dolby Vision it tells me my TV doesn't support, but I can see a screen.

4K HDR - HDR10+ at 30 FPS which it doesn't recommend

4K TV is available which I Was going to try next.  Just trying to figure out if I need a newer HDMI cable for the Roku to see my TV available options?

What options should I choose?

Well, the latest HDMI standard is 2.1b.  If you are going to get a new HDMI cable, get one with one of the latest standards (at least 2.1 or 2.1a) and make sure it is a certified one and not one of the many generic brands out there that you don't know what you are getting. 2.2 is due out sometime in the next few months.

I have a new Samsung OLED.  It states that all HDR settings are active out of the box.

Looking at the Roku help file, I did have to enable something on  my TV.

Go to Settings > General > External Device Manager > 

There was something called Input Signal Plus.  I turned it on for the HMDI port that has the Roku and it gave me a new option for 4K HDR10+

Looks like more TV manufacturers have a setting for this.
