Is this an Oakleaf Hydrangea or something else?

Astro

I've come across a plant and most plant ID apps suggest it is an Oakleaf Hydrangea, can anyone offer a confirmation one way or another. Thanks

Something else! Not Hydrangea quecifolia.
It looks like Viburnum opulus.
Flowers then fab berries.

Certainly not oak leaf hydrangea. It looks like this 

Superb autumn colour on them too

Great I'm pleased with that, it's at my place of work. I actually have a viburnum opulus at home,though it's new and I didn't make the connection 🙃 .

@Fairygirl - that is a really pretty shrub.
Do you keep it that size or is it not fully mature yet?

Fairygirl

That's from a few years ago. It's probably about full size now - a bit bigger than that. It doesn't need pruned, although you can certainly do that. I have another one which I had to move, so it was pruned a good bit for that.  I only take off any damaged stems, or ones that are in the way. 
The autumn colour is the best bit, although the flaky bark on the stems is also nice.

Pics below show Hydrangea quercifolia  Pee Wee and Snow Queen.
Leaves, flowers and autumn colour were lovely lovely. .

@Silver surfer - beautiful. 
I think you kindly posted a photo of your Viburnum Sargentti Onondaga (spelling?) to give me an idea of what mine should grow into.
It's a lovely shrub and hopefully it will become as nice as yours.
