I know that you’re primarily engaged in trying to match a real Phillips TV that you have these days but whenever you have time it might be a nice escape/vacation to program some Shadow (Dot) Mask presets.
That is because it is the brightest Mask we can emulate at 4K due to the lack of the ability to draw the black mask holes themselves at the fine pitches that would be required.
I know that one of the most difficult aspects of doing these things is getting things to look realistic while maintaining adequate brightness and gamma levels. Well Shadow Mask should make that a bit simpler and allow you to enjoy more time playing as opposed to tweaking.
