Maybe someone with more knowledge of the GWR and "regular" red genes could jump in here as I'm not particularly familiar with the 'greenies' and their breeding.

My best guess (and that's all it is) is that you may have some sort of 'co-dominance'. For many genes it is either dominant or recessive, but sometimes for some genes each gene of the pairing expresses itself. (the example I've seen in talks about genetics is where a red flower and white flower are crossed and instead of red or white dominating, for certain species you'll get pink.)

Because from my limited experience, that tomato is not a r (R being Red-flesh), and various forms of r express less lycopene giving a range from orange to yellow to almost white (and possibly affected by modifier genes).

To me that tomato is trying to express red, and is being 'blocked' somehow.

Anyway, if you haven't seen it, you might want to look at this blog/article:
