BD luma, DVD chroma looks the most overall balanced to me.

I agree with you, but as I explained, it's not possible to use this technique, as the DVD and BD cropping are different (take a look at the "Neeo with green beard" screenshot...); as DVD luma + ColourMatch chroma is, maybe, 95% or better close to it, without side effects, this it the reason I decided to use this last method.

The only thing that it needs fixing is the contrast.

I could set the contrast lower to match better the DVD, but what if the DVD contrast was wrong?

We need more input from other people.

I agree.
