That IS very interesting!
We haven't bloomed any Phrag. La Vivace Epicure Phyllis D Turner that look anything like that, but this plant is definitely 50% klotzscheanum, and the shape looks like Phyllis D Turner! but why the color change? Have you been growing it at cooler or warmer conditions than normal? That can have an effect on the color.
It is possible that some of the red pigments came from klotzscheanum. look at one of our Phrag. Nights in White Satin (which is 25% klotzscheanum, 25% popowii and 50% wallisii). This plant has a lot of pinks and reds as well:

So one possibility is that it is indeed Phyllis D. Turner, but either you have two different seedlings in your container (same cross, but 2 different genotypes), one is more green (and this is the one that bloomed before), and one is more pink. Or the difference in color could be due to an environmental difference (warmer or cooler temps, or you may have sprayed the plant with some chemical like an insecticide or fungicide which had an effect on the flower color).
The other possibility is that it is a different cross, so klotzscheanum x ?? if I would guess something else, it would be by schlimii or a schlimii hybrid.
