Sibling differences? Lc. Angel Love x C. skinneri

[kikitastrophe]

The first photo are the blooms from this October, and second photo are new blooms from now (November).

My Aunt believes the flowers have been getting more purple; she says previous bloomings were almost white and she's had it for years.

Do blooms change over time in Cattyleyas or do you think the difference is due to siblings with slight differences planted together and blooming at different times?

Thanks!
