Any question answered...

Is there a reason why most of the latest LED bulb models are not available in the UK? I keep looking
for them online and they only ever become available in the US. Philips and Cree now even updated
the latest ones with never versions but still nothing...

Too much demand at the component level?

Maybe the consumer bulb demand can't compete with the demand from other industrial channels, e.g automotive applications, commercial lighting, hipster bike torches...

Surprised Philips models aren't more available as they're an European company and are vertically integrated from SMD component up to consumer products.
