I tried watching an HDR video on YouTube Edge browser full screen which supports HDR and the quality gives me options 1080p60hdr, 1440p60hdr and 4k60hdr but it doesn't actually change the TV to HDR like it should. Watching the same video on edge YouTube 4k60hdr and then on YouTube app through the Smart TV or fire tv stick 4k and it's clear edge isn't HDR.

So what results did the HDR calibration give you? What brightness did it calibrate to?

Also, if the TV really doesn't enable HDR but allows you to play HDR content, it should look quite off. Unless there's some internal tonemapping enabled on the TV that would take the HDR signal and tonemap it to SDR, in which case you should probably look for such option in the TV settings or in the manual at least.

Some TVs also enable certain features based on the specific mode, as in they allow different settings and options in different modes. I have a Samsung smart monitor that essentially uses their TV OS, and out of Game mode, the HDR defaults to tonemapping to 1000 nits, but in Game mode, it enables HGiG by default (the option is only available in Game mode, too), so there's no tonemapping at all, but if I disable HGiG, then it tonemaps to 4000 nits.

Is this the TV in question?

Yeah that's the TV. 55 inch variant .It looked like a calibrated HDR image without the TV being in HDR and the max luminance 820 though maybe could've gone with 800. And yeah the image does look off cause the TV is not switching to HDR. and it doesn't look like there's an option to switch to HDR manually the tv has to do it. That would fix everything. I've looked through the manual and all throughout the settings and there's nothing. The hgig option only shows up when game mode is turned on and if it detects HDR. I have to hold down a button and go to menu and it'll be turned on.
