Your display could be pulling on red more than blue, and if you adjust saturation, it's drawing all the colors in a direction that's already skewed. Again, you're entitled to an opinion of the image, but it's in reference to your visual taste and NOT to what the data actually intended. If you care about ( the right ) Color, get an xrite, w/ 3dlut correction, this is a non-issue.

Can't figure out why some 4K HDR remuxes have a stutter during pan scenes in fullscreen (exclusive and non-exlcusive). If I don't full screen, it's smooth. Claims repeated frames every 8 minutes, and my 2080Ti isn't even at 50%. No dropped frames...
EDIT: It's caused by having MadVR set refresh rate to 24hz. I tried setting 2160p23 and 2160p24 but both result in a slight stutter. Leaving my LG OLED in 60hz results in smooth, jutter free, motion during pans and much less blur. 24hz playback should be superior though? Any ideas?

Try setting present frames in advance to 1. That has fixed the issue for many. Using D3D9 presentation with 8-bit RGB output rather than D3D11 presentation has also fixed the issue for others

There's no point using a meter if people can't first correctly setup their graphics pipeline to get it to at least display in the most accurate existing mode, which is what is being discussed here. 3DLUTs are for correcting inaccuracies in the display, not massive symptoms of bad configuration of the source.

I have 19.9.3 and 436.51 installed now (respectively on the two machines) with Win10 1909. I think the main issue is an HDMI metadata error (the important part is the TV's OSD banner with the signal info): NV HDR - AMD HDR - AMD Win10-HDR. Windowed/exclusive doesn't make a difference with AMD HDR (I also tried turning the Game Bar off on the AMD system for this test). Quote:
On top of that, while using any calibration, no matter how bad, the same source should produce the same colors. The relative comparison makes some sense in this case anyways. I can't get a decent HDR calibration done with the AMD notebook as a source device if it distorts the colors and limits the gamut to Rec709. You can surely agree with that.

The key point to understand is that upscaling does not increase detail and introduces artifacts. After upscaling each pixel represents less detail compared to the source pixels, so GPU effort is much better spent on earlier scaling steps. As you increase the resolution each individual pixel becomes less and less important.
You want NGU to start with the source pixels, not after lanczos, so it can preserve maximum detail and avoid upscaling artifacts. The second doubling step is much less important than the first. I like using NGU high for chroma upscaling (the first doubling step for chroma) but using NGU medium for the second and especially NGU low for the third is much less important. By the third doubling doubling step I am forced to agree with the sentiments of tp4tissue, there really is no practical difference between using NGU high and lanczos3 or bicubic.

do you have anything set in the TV calibration section of MADVR, mine is now set to off, I previously had to calibrate to BT2020 due to a bug with AMD drivers with sub 60hz SDR material but i've never had an issue with HDR and still dont, all my comparisions look the same.

Hello. In madVR devices->calibration set "disable calibration control for this display and check "disable GPU gamma ramps".
Can you check on your TV there is a choice of colour gamut (BT.2020 or DCI-P3) for AMD HDR? Thank you.

A couple of other things: - I'm not using the latest beta HDR stuff, just using stock MADVR v0.92.14 - I have passthru to display set and no other options set apart from send HDR meta to display - i have calibration turned off and gamma ramps unticked. - my TV behaves oddly when I set it to PC mode, colours are all off, i havent played with this for a while but thinking back I may have been getting something like you are, what is your TV set to as the input, mine is configured to just standard HDMI so not set to PC, bluray etc, try a different input name as this can actually change how the unput works, for instance when in PC mode a lot of my motion controls are disabled. I gave my HTPC a thorough workout this weekend gone, watched loads of movies, SDR and HDR, not issues are at, no drops, repearts, black screens, crashes, odd colouration.

yeah I was right, check this out, the top one is with identical settings PC, TV and MADVR with my TV input set to PC mode, bottom TV set to "HDMI", I also set it to "BLURAY" and it was also ok so, no idea why this is though but it looks like identical behavior to you, try changing your input mode.

Don't know why but NGU doesn't work for image upscaling with DVB-T sources. This is on Windows 7 with v.0.92.17 and JRiver or MPC-HC. It works for chroma upscaling, but for doubling when I select any NGU the OSD shows super-xbr.

What are the proper settings for 4K HDR BD Remuxes on an LG OLED? I have NVIDIA drivers set to "RGB Full" and MadVR set to "10bit or higher". I still see some banding in some scenes scenes. Maybe it's normal, but I don't remember seeing them on SDR 1080p BDs.
