McCreed I was referring to how this bridge, TOM style, has a fixed radius while the other bridges I've worked with don't have that (each string/pair of strings is adjustable up and down, the default is all of them flat) and the choice to level the frets with a radius block or with a flat block, getting the frets closer to flat than radiused. I realise now that even with a flat block, it would still mostly follow the radius...

In my limited experience with my own guitars, I've always tried to get the string height the same on all strings but it occurred to me that I would have to match the fretboard radius with each strings height to get that. I've just gone and checked on my guitars and despite trying to get them the same, I see that they vaguely match your diagram, the treble side slightly lower. This will be what I aim for then as it's comfortable.

Thanks Mark and Robin, I'll leave it as it is then (levelled with a radius block)
