Some use a file that certain commercial software can create and upload to the set and the TV bases the DV implementation on that. Others use a system that depends on a baseline Rec. 709 2.2 gamma calibration to layer HDR-10 and DV over. I don't believe TCL uses any of this.
Thanks for your help, it's greatly appreciated. I am sure this info is out there somewhere and I've been trying desperately to find it, but haven't really found all the answers to my questions in one place.
So when Dolby Vision is used will it completely ignore the white balance/cms changes I've made to the HDR profile? Is it best for me to not change anything?
With the CMS artifacts, I haven't seen any myself so far after trying the same ones rtings.com used with their calibration but I'll have to keep a look out for them. Do they appear both in SDR and HDR?I read some remarks particulary with lg's where changing CMS resulted in noticeable artifacts to color test slides and in real content, particularly with people's faces but I can't say I really know what I'm looking for.
Eventually I'll probably look to use a htpc again, if anything for the want of being able to use 3d lut calibration, but right now I'm just looking for a casual way to get the best I can without spending a lot of money.
The Colormunki is on sale right now for $100 which is certainly a very attractive price but I worry I'll regret buying it instead of the i1 Display Pro. I know the limitations with read speed and commercial software compatibility, but will mainly be using either hcfr for the TV and displaycal for my computer monitors.
Should I worry about the future when it comes to calibrating Dolby Vision? If there's currently no way to calibrate it on my TV, will there ever be? I had assumed you could currently, at least with Calman but was unaware that it only supported select TVs.
As for white balance calibration, do most people use a different customised preset for HDR calibration or typically use the same custom one created for SDR? Do they opt to correct no white balance at all with HDR using instead another stock preset?
I read a calibration review of the TCL 6 series and the calibrator used the same white balance for HDR, which was better than stock but still had some pretty large errors. In particular he corrected a large red push in SDR mode that resulted in red rolling off sooner in HDR.. But he used the same preset for both instead of basing HDR and SDR white balance controls on different presets.
