IPhone 11 Pro significantly slower LTE performance than a Pixel 4 - LTE Advanced not supported?

I have an iPhone 11 Pro and recently tested out an unlocked Google Pixel 4 on the same SIM. When using the O2 SIM on the Pixel it noted it was on "4G+" which I understand is also known as 'LTE Advanced'.

 

Using the same Speed Test app on the iPhone and Pixel, it showed a reliable 3-4x faster download and upload speed on the Pixel than the iPhone in the same location.

 

Is this because the Pixel 4 supports more of the LTE bands O2 uses than the iPhone 11 Pro?

iPhone 11 is rated CAT16 for LTE- A, whereas the Pixel 4 is rated CAT 18.
This gives the Pixel a theoretical advantage of around 180mbps for download speeds (dependent on network capability).
