A late answer to this question, and the problem with my TV apparently only going up to 400 nits. I used Metadata created using the AVTopController in Calman.
BT2020 (AVI) Format: RGB
Mastering Primaries: P3
Mastering WP: D65
Max MDL: 1000
Min MDL: 0.005
MaxCLL: 1000
MaxFALL: 400
HDR infoframe: 87:01:1a:74:02:00:c2:33:c4:86:4c:1d:b8:0b:d0:84:80 :3e:13:3d:42:40:e8:03:32:00:e8:03:90:01
AVI infoframe: 00:E8:64:
5D:00
But, I don't like that AVI infoframe. ["5D" = 2160p24 which is a lie for my video card. So I used "10": 1080p60]
AVI infoframe: 00:E8:64:
10:00
I then pasted these manually into the Integral GUI app and saw the TV switch into HDR10 mode.
I was doing experiments last night with the Raspberry Pi's output vs my laptop's output.

I will have to try again (hopefully this weekend) and pay more attention to all the settings in the Calman metadata creation boxes, and what I set in the HDFury PC Utility for AVI Infoframe too. It does sound like I got one of the settings wrong. I wasn't too worried at the time because I remember I've measured 742 nits last year. But there are so many different things to remember to do, all in the perfect order, and one tiny mistake and it's all wasted.

If you manage to make this work, it will require a bit-perfect 1080p60 full-range output from your VGA, it will mean can output accurate levels, for RGB, if it will work.
Right. If I understand you correctly, what you are saying is that the Dolby Vision pattern source window in Calman can be used as a way to test if the laptop is bit accurate? Instead of all my pain of comparing readings - it's a proper full test of bit accuracy?
In that case I have a failure because on the "test" page I got a red/yellow pattern on the TV and it didn't switch into Dolby Vision mode.
Tyler mentions this only very quickly here:
So, I think the answer I have now is that my laptop isn't bit accurate, and/or that method simply doesn't work.
Back to my problem of only getting 400 nits - I turned on TPC in the service menu, all the processing was turned off (Logo luminance adustment, dynamic tone mapping, dynamic contrast etc). Is there anything else that might be causing it?
