Thank you all for your comments.
I thought because of hybridization and standardization of care for the general public it might be too difficult, but worth a try as the lips are just so different.
Just for my own interest I did a bit of looking while waiting for replies to my question. I found a web page,
Les Orchidees Phalaenopsis botaniques et hybrides primaires
with pictures of different species.
The philippinensis has the same type lip but the schilleriana has the same petal and sepal form as the one remaining bloom on one of my new acquisitions.
I realise this knowledge wont change care of my plants, but the hunt for information is good for the mind.

It is strange the plants disappear, it would seem unlikely the wholesaler gets them back, it would be a logistical nightmare for them.
I have heard a commercial Cymbidium grower say that the big growers/wholesalers in Europe have no interest in returning plants to their greenhouses for reasons of logistics, space and hygiene, so I would think the same would apply here. Possibly they get snapped up quickly by local buyers....I know they do here!
An orchid growing friend said they had bought some reduced phals at our local regional Bunnings but despite random visits I could never seem to find any....I guess other members of my local orchid club got there first 😁
So I changed tactics, I got a mini phal for $5 by looking on the display shelves and finding one that had no flowers and asking the cashier if they would reduce it.
My latest purchase was a case of right time and noticing the shopping trolley with a few reduced phals.
Maybe if you ask the garden manager at your local Bunnings they might keep a few aside for you or at least give you call before they put them out as reduced or bin them.
