I see those odd levels, not 5% levels, and that's what is getting controlled by CalMAN when I AutoCal or do manual tweaking.

Sorry, you meant the TV's settings menu, so yes I imagine so. But it's speculation at this time unless Samsung can clarify.

Is it ever advisable to adjust the CMS settings when doing a manual OSD settings HDR calibration for Samsung sets (that don’t support autocal)? Or should the color space be left to Auto and only white balance (2 & 20 pt) adjusted?

Definitely give CMS a try.

Samsung only allows CMS access if you switch the Color Space setting to Custom (as opposed to Auto or Native) and then set either DCI-P3 or BT.2020 as the color gamut.

Now I believe the color gamut setting in there is actually setting/forcing the color gamut, as opposed to just allowing you access the CMS settings for that gamut (kinda like how changing the 20pt white balance scale between 5%,10%,etc. isn’t setting anything, just allowing you to configure that setting). But I’d be happy to be corrected here.

So then if I’m trying to adjust CMS during a manual HDR calibration, do I set Color Space Custom and BT.2020 gamut? If so, what’s the point of DCI-P3 gamut?

Yes you want to use Custom. You might want to try both BT.2020 and DCI-P3, to see which gives you better accuracy. On the Q90R, using DCI-P3 produces better results, even though CalMAN calibration target is BT.2020.

Few questions

1. What do I need for a Samsung Q80 and is the auto calibrate possible?
2. What is the best at home pattern generator without spending tons?
3. I see some pattern generators are on blue ray, how does this work and is it auto?
4. What meter is the best and do you really need two meters?
5. My video single is going through my Denon receiver to my tv. Are you calibrating Just the tv or the receiver also?
6. Can you calibrate the SDR and HDR10? Do I need anything additional to do so.

Thanks for all the help.

Autocal isn't currently supported for the Q80R, but see this post for hope, although I wouldn't count on it until a new CM version and firmware supporting it are actually available. For SDR calibration, you can use the Client3 pattern generator for free, including with Autocal. You can use test patterns on blu ray or USB drive for manual calibration, but not for Autocal. You can use HDR test patterns on disk for manual 2 pt white balance and CMS, but not 20 pt white balance. If Autocal does become available for Q80R, I assume it won't support 20 pt white balance, same as other 2019 Samsungs have lost out. If your pattern source goes through your receiver to the TV, then in effect you are calibrating the device chain, but only altering settings in the TV. If you want to do HDR calibration, you'll probably want a meter that can do more than 1000 nits HDR, since it looks like the Q80R can do ~1100 nits.
