Strange HDR Calibration on 4K TV and setting is not saved locally

I currently play ME:LE on 3 different setup. An Acer CG437K at my home office, I also play on my Samsung Q90T in the living room from time to time and I play on a Aorus FV43U (used to be a Vizio M437-G0) at work and the HDR calibration is not saved locally but on cloud which means that I have to re-calibrate every time I use a different setup.

I have now played ME:LE on 2 4K HDR monitors and 2 4K TVs and the HDR brightness calibration while pretty dead on for the monitors are way off on both TV and results in dark images.

Acer CG437K HDR 1000 monitor. HDR Contrast +1, HDR Brightness 1000

Aorus FV43U HDR 1000 monitor  HDR Contrast 0, HDR Brightness 1000

The 2 setting are pretty much dead on to the monitor spec and the image in game looks great and the setting is close enough that I usually do not re-calibrate when bouncing between the 2.

The HDR Brightness calibration will act strange on 4K TV with local dimming resulting in HDR brightness settings way above the unit spec and a much darker image while in game.

Samsung Q90T HDR peak brightness is 1400 cd/m2. Under HDR Brightness calibration. The N7 logo will not disappear until setting is at 5300 which results in a much darker image in game. Setting HDR Brightness to 1400 results in a normal image (when compared to the same image on either one of the monitors).

Vizio M437-G0 HDR peak brightness is only rated at 450 cd/m2, Under HDR Brightness calibration, The N7 logo will not disappear until setting is at 2300 which results in a much darker image in game. Setting HDR Brightness to 450 results in a normal image (when compared to the same image on either one of the monitors).

I think the local dimming is affecting the calibration so users might want to turn off their local dimming while doing the calibration or just look up the peak HDR brightness for their TV and just set it as the HDR Brightness despite the N7 logo still being visible.
