Some camellias produce sports on some branches, which results in different looking blooms. However, that does not mean that if you buy another shrub, the new one will necessarily produce sports too. It may but it is not written in stone.

Do you know which one of those blooms is the "correct" one for that bush? If not, I would try to ask the previous owner.

I would say the 90% of the bush is the marbled, striped pink shown in the top picture. It's in full bloom right now and so beautiful. I sure hope I can track down the name!

Have a look at 'Betty Sheffield Blush Supreme' and 'Betty Sheffield Supreme', and see what you think. Most of the Betty Sheffield sports are fairly unstable, so you may get a variety of colorways and bloom forms on the same plant.

It may not be one of the Betty Sheffield tribe, but it's worth considering. Unfortunately, I didn't see any foliage pix online to compare with your photo.

It's lovely, whoever it is,

Thanks! I had a look at Betty Sheffield and thought it was close, but not quite right. I did some more looking around online and think I've found it! Spring Sonnet! It's the closet thing I've found, anyway!

Yes, 'Spring Sonnet' does look like a very good possibility. A Google image search might be useful to get an idea of how flowers of this cultivar can vary. You have a better idea than I do how representative your photo is of typical blooms.

Whatever it is, it's lovely. Enjoy!
