Good morning!
I posted this in the plant ID, before realizing that we have a Hibiscus forum.
I've never grown these beauties before, and I have been trying to research them since receiving this as a gift. I am smitten by it, especially since blooming. The color of the leaves was enough for me, but when it bloomed. Wow!
In my search, I came across the H. cooperii, being the only one I found to be similar.
Can anyone tell me if I'm correct? Or could it be something else?
I didn't want to add it to the database if it was not correct.
Thanks so much, in advance for looking.

Any opinions?
Or lead me to another possibility?

No opinion?
No thoughts? Of what other variety it might be?
Should I gather that it really could be "cooperii"?
Anyone?

I am surprised that nobody answered you, but it is a very slow forum.
Yes, yours is a 'Cooperi'. There are many cultivars, the most common one is 'Snow Queen', then there is 'Snowflake' (now sure if it's just a synonym): they have white variegation. 'Hummel's Fantasy' has almost white leaves.
Then there are tricolored ones with white and pink like
'Roseflake' (it is more robust and larger then white-variegated with older leaves turning dark burgundy). Recently popular 'Red hot' (very often with totally pink leaves). And some others, like 'Aussie Queen'.
The flowers are all similar very bright intense red with separated single petals.
here is a good article about it:
