Dendrobium Dawn Maree Splash (No Splash Now???)

On 8 December 2022, I created a thread entitled Dendrobium Dawn Maree Splash. I am somewhat saddened as this plant is no longer producing blooms that are splash/peloric. Why? The previous 'splash' blooms were so beautiful. Can anyone tell me why this is happening? I can guess that the answers will be speculative and only guesswork, but I still would like to hear your comments and suggestions. Please keep in mind that the plant has gone through quite a long journey in the last 4 months having moved from the original location in Chiang Mai to a different location in Chiang Mai and now to its current home in Khon Kaen. All three Thai locations have basically the same weather and climate conditions (hot and humid).

I have included pictures of flowers with 'splash' (8 December 2022), with 'no splash' (24 March 2023) and 'faded splash' (26 March 2023). I currently have one cane that is producing 3 flowers (two with no splash and one with faded splash). I also have one flower (not pictured) that will be opening in a couple of days on a totally different cane. The older pictures with the full splash are flowers from a different cane. Since it is a larger plant(s), I realize that there is the possibility that there may be more than just one plant involved here and there may be multiple plants potted.

I probably shouldn't even be concerned about this and just accept the plant as it is, but I am sooooooo curious. It is my favorite orchid plant.

Thanks.
