The problem with rose tails is that they might not show any defects. Take this male as an example;
in your opinion, how rose is this male? Physically, he doesn't look that bad of a rose. But it was this male that started my rose problems for generations. And due to lack of knowledge on roses at the time, I added more rose genes and made it worse.
If I have to grade the "rose-ing" I'd give your male a 5 - 7. His small caudal and the female's form may suggest he carries defected genes. But that's just a guess. He may not carry the bad genes - considering that breeders now know rose potential thus would probably not inbreed them.
Females: look at rose female's dorsal. It opens like a fan. That's what you're looking for. The second female's dorsal leans to the back. Further her wide caudal suggests that she may have multiple rays which would add to the rose-ing. But a better picture would help - better judgement.
