As promised, iPhone and Oly 5iii photos. Sorry if these don't come out too clearly. I'lll try to explain as much as possible in the accompanying comments. For info., despite shooting semi-pro in the past, I'm now retired so am a family / amateur / fun photographer. Photos these days go on digital photo frames, the annual calendar from Vistaprint, eBay and there's the very occasional print, no bigger than 7" x 5". Having said that, I do like to get the best quality images at all times. Best is, of course, a subjective term.
These comparison shots were taken on the coast of Cornwall, England at the tail end of one of the hurricanes (Eunice?) that hit the UK in February '22. On the cliff top the wind was so strong I had trouble standing still let alone holding a camera / phone steady. Thankfully it was blowing onshore else I'm not sure I'd be here.
First up, SOOC and SOOP images, side by side in LR Classic. Oly ORF = more accurate rendering of the colours of the sky at the time. iPhone HEIC = IMO a more immediate and aesthetically pleasing image despite being a factually inaccurate record of the scene.

I ran the ORF through DxO tweaked it a bit and and applied DeepPRIME. It's not easy to see in the screen grabs but DxO image is predictably sharper and the contrast & colours faithful to the reality of the scene. Yet everyone to whom I show these prefers the iPhone image.

To return to the OP, the Oly and the iPhone are both 'worth' it: the former for creative latitude, the latter for convenience. YMMV.
If anyone wants to 'have a go' with either or both these images, I can make them available for download. Start a private conversation with me via the forum and I'll send the link.
